Unusual Seismic Recordings from Mount Rainier Glaciers

This is Steve Malone with the Pacific Northwest Seismic Network located at the University of Washington in Seattle. We operate seismographs throughout the Pacific Northwest and have three located high on Mount Rainier. We often record seismic events from all of our glacier-clad volcanoes that we associate with glacier motion, i.e. "ice-quakes." However, since about May 20, we have detected a strange set of these events coming from the upper Winthrop Glacier. We are calling these small events "clones" because the seismic waveforms from one event are near-duplicates of those from other events indicating a repeating source. They also seem to occur at very regular intervals.


The interval between events is often as short as every 3 minutes but changes from time to time and has been as much as 15 minutes between events. We think that their magnitude (on the Richter scale) is about M = -1 (i.e., 8 orders of magnitude smaller than the Nisqually earthquake of 2001).




So, what are these puppies? We think they represent small periodic slips at the bed of the glacier. Perhaps there is a large rock embedded in the bottom of the glacier and as the glacier moves it scrapes this rock along the bed, only a few mm in each slip. But why are they so regular in time? Maybe water pools up-hill of the rock until it slightly lifts the glacier allowing the rock to more easily slip and this then drains that small pool of water starting the process over. We think that water has an important influence on glacier sliding but don't understand the mechanism very well.


How can you help? Anyone climbing Rainier on the east side (upper Emmons or Winthrop Glacier routes) may see or hear things that would help us pin these suckers down. Please let me know of anything you think may be out of the ordinary (sounds, sights, feelings???). Particularly those of you who have been in this area before and can compare what may be different from previous climbs. Our best guess where these originate (based on stacking 4000 individual events to get the best relative seismic wave arrival times at six seismic stations and using a 1-D seismic velocity model with station elevation corrections, blah blah blah, other scientific mumbo-jumbo) puts the location at 46.85950 north 121.7610 west (i.e., 2.5 km WSW of Camp Schurman or 3.4 km NNW of Camp Muir or about 600 meters up from the top of Russell Cliffs).

To see these suckers yourself check out our "webicorders" at:

and click on the date-time for one of the high Rainier stations (RCS, RCM, STAR). The small blips that have about the same size and shape are our "clones".

New Irishtown Mixed Route, Dirty-T M4+




Laura Hahn seconding the new route Dirty-T M4+
Laura and I put up a new mixed line at Irishtown. Its located a hundred feet or so left of Dynamite. There is a line of ice in between the two mixed lines named Pale Wildwood Ice Tower - WI4. Its not quite in yet, but should be touching down by mid next week. Dirty T M4+. It climbs up through some ledges and face passing 3 bolts. Climb up through a small overlap to the ice and finish it up with turf to the trees. Lots of fun climbing for almost anyone. Great introduction for the climber looking to combine rock and ice.

Turf to the top
The route name came from all the dirt that came off of the cliff and ended up all over me. It started out with me being clean and the route being dirty and ended with me being dirty and the route being clean. Enjoy!

Brevet Season

Brevet Season Kick-Off Party, Ride Studio Cafe

Over the weekend, local bike shop and cycling club Ride Studio Cafe hosted a group ride followed by a Brevet Season Kick-Off Party that lasted well into the night. Organised by the RSC and cycling legends The Blayleys, this event included food, drink, a bike show, and an information session about various aspects of randonneuring.




Brevet Season Kick-Off Party, Ride Studio Cafe
This event struck me as significant on a number of levels. It was a coming together of the worlds of road racing, randonneuring and casual cycling, which rarely happens in other communities. It also showed just how much local interest there is in randonneuring. The room was absolutely packed and by the time things got started it was almost impossible to move. No one expected such a turnout.





Brevet Season Kick-Off Party, Ride Studio Cafe
Though many beautiful and unusual bicycles were brought in for the bike show and contest, it was impossible to photograph them due to their sheer proximity to one another. Frames bearing the marks of Weigle, Vanilla, ANT, Rawland, Rivendell, Sketchy, Gunnar and Seven were a common sight, as were refurbished vintage mystery frames. The glitter of hammered fenders set the room aglow. Saddlebags swayed to the soft French music that played in the background. Map sleeves glistened. Leather saddles of at least 4 different makes flaunted their rivets and cut-outs.Light and heavy, racy and sedate, with integrated lighting and without, rando bikes filled the entire room and spilled outside. Waist-deep in a sea of lovely bikes, yet unable to photograph them... oh how I suffered! The winners of the bike contest were a stunningly crafted JP Weigle, a refurbished vintage Raleigh, and a customised Seven rando bike (this one).




New England Ranonneurs, RSC Brevet Season Kick-Off Party

Last year it took me a while to understand what randonneuring really was, and I suspect many readers might like to have it explained. French in origin, randonneuring is defined as a "noncompetitive, timed, endurance cycling sport." It involves riding in organised long distance events, with the goal to finish within a specific time frame. The rides are unsupported (no van with supplies and mechanical help to follow riders around) and take place regardless of weather conditions. Control points along the way ensure participants cover the entire route.




Official randonneuring events (aka randonnées) are sanctioned internationally by the Audax Club Parisien and in the US by Randonneurs USA. Our local organisation here in Boston isthe New England Randonneurs (NER).




The shortest type ofrandonnée (petiterandonnée?)is called the Populaire, and it is 100km - a metric century. But the prototypical randonnées are the brevets - rides 200km or longer. Local organisations will usually host a brevet series starting in spring, consisting of 200km, 300km, 400km and 600km rides spread out through the season. Hence, the Brevet Season.




Other types ofrandonnéesinclude the Flèche (a 24 hour team event, described very nicely here), and the so-called granderandonnées, the most famous of which is the 1200km Paris-Brest-Paris(for some time there was a local granderandonnéeBoston-Montreal-Boston, but sadly it appears to have been discontinued). The schedule for all the local randonnées this season is postedhere.




Brevet Season Kick-Off Party, Ride Studio Cafe

A number of well known local randonneurs attended the Brevet Kick-Off Party, and it was a pleasure to see them in person.




Emily O'Brien, RSC Brevet Season Kick-Off Party

It was particularly excited to spot Emily O'Brien - a woman known for riding long distance on fixed gear, eating pickles, and making custom bicycle bags named after pickles.




Cris C., RSC Brevet Season Kick-Off Party
I also finally met a few people whom I'd previously only corresponded with - including Cris C., who arrived on his well-loved ANT.




Matt Roy/ MM Racing, RSC Brevet Season Kick-Off Party
Presentations were given byMelinda Lyon of the New England Randonneurs, Pamela Blalock, andMatt Roy of MM Racing. Matt was at a disadvantage in that he went on last and it was already quite late. But I am so glad I stayed for his presentation, because he is an extremely engaging and charismatic speaker. At 10pm, Matt's talk made me want to immediately get up and ride a few hundred miles - whilst meticulously following his instructions of course.




Brevet Season Kick-Off Party, Ride Studio Cafe
While I find the idea of randonneuring exciting and romantic, I doubt that I can actually do it. The routes are hilly and challenging, and the people who do these things are extremely strong riders, no matter how much they might downplay it in conversation. Randonneurs tend to make a point of being inclusive and assuring others that "anyone can do it," and they honestly believe it. They also have a habit of describing rides in a way that makes it seem all about the scenery and camaraderie, conveniently leaving out the part about it being difficult! But in fact it is very difficult, and I am not a sufficiently strong cyclist at this stage. It is also a must that participants be able to fix their own mechanical problems, since there is no support. While I have the know-how, I cannot physically work on my bike and that presents a problem. Finally - and I hate to say this, but it's true - I am simply not committed enough. Though I ride a lot, I do it on my own time instead of planning my life around rides that take place on specific dates. When push comes to shove, personal things have priority and in the past it has been very difficult for me to commit to organised cycling events. For serious randonneurs, their lives basically revolve around the brevet season, as a great deal of commitment is required to both take part in and train for the events.



Some day I would like to take part in a brevet (or a flèche - those sound like so much fun!), and I certainly do not mean to discourage others from doing it. It's just that there has been such a tendency to romanticise randonneuring and to contrast it with racing, that the popular image of the activity does not, in my opinion, adequately reflect how challenging and demanding it actually is. It's good to go into something with realistic expectations.




Brevet Season Kick-Off Party, Ride Studio Cafe

As you can see, the Brevet Season Kick-Off Event has given me a lot to think about. More than anything, I am still overwhelmed by how significant it felt to be there. We could practically feel a new era dawning as more and more people filled the room (several of us mentioned that independently so I know it wasn't just my overactive imagination!). While it doesn't mean that the local population will now rush en masse to join the New England Randonneurs (though it's a great idea to support them), I do think it's indicative of a growing interest in a particular type of cycling: long rides on bikes that are fast yet practical, and without an overt competitive element. It's the kind of cycling I like best so far, and I appreciate that it is so well supported locally. More low-light pictures of the event here!

Renting the KHS Green

Earlier this spring, I was delighted to discover that the KHS Green can be rented from our local Cambridge Bicycle. The cost is $25 per 24 hour period. My darling Co-habitant and I rented a men's and a ladies' and took them along the Charles River, as well as through some streets of Cambridge, Somerville, and the center of Boston. We went to some of the places we usually frequent, to see what it would be like to get there by bike (it was great!). And I intentionally wore a skirt, to determine whether this would present any problems (it did not!).



Renting a bicycle similar in style to the one you plan to purchase is something I very much recommend. It has certainly helped me hone down my preferences. For one thing, the 3 speeds were just barely enough for Boston, and we did not even go to the particularly hilly areas. So now I know that 3 speeds are a minimum for me, and that a single speed bike is out of the question.



I have also discovered that I love the coaster brake. Despite never having ridden a bicycle with this braking system, I got used to it immediately and found that, especially when riding through the city, it gives me the optimal degree of control. It is also somehow less stressful to use than the hand-brakes, especially if you are a person who panics easily when other bikes or cars are close to you. Though it was comfortable to have the front-wheel handbrake there, I barely used it and relied mostly on the coaster brake.



Another pleasant discovery was that, after 12 years of not touching a bicycle, I was not as out of practice as I feared. I had tried other bicycles in bike shops over the past year, but did not feel sufficiently comfortable with any of them to ride them on the street. The KHS Green is the first bike I've tried that has made me feel okay with actually riding it "for real". And as soon as I started riding the bike, it all came back to me naturally. The upright sitting position was an absolute joy, as we breezed past the ridiculously picturesque blossoming cherry trees.



After riding the KHS Green for an entire day, I would describe it as a good bike. When going over cobblestones, the ride can be a little bumpy and it is missing some components that my bike would ideally have, such as the dress guard and a full chain enclosure, but for the price it is a great deal. If my budget does not allow me to splurge on the likes of Gazelle, the KHS Green may be my bicycle of choice.

On the Vine


This was a big watermelon. We guessed it at about 20 pounds. Biggest we ever raised. And it was good. The next photo down is of it cut open.

Depending on who you speak to, it is either the most over-rated vintage bicycle in existence, or the Holy Grail: The classic Bianchiin the legendary "celeste" green.






[image viaSpernicelli]


The first time I saw a true vintage Bianchi wasa couple of years ago,in Austria. It was many decades old and partially dilapidated, hanging in a dark corner of a stuffy bike shop - among dozens of other classic Italian bikes. Still, the Bianchi was the one I noticed. From across the room, I walked toward it with a flutter in my chest, my hand already stretching out to touch the lugwork. Amore.

Started in Milan in 1885, Bianchi is described asthe world's oldest bicycle company still in existence. Though it has always produced a wide variety of models, Bianchi is best known for its classic racing bikes - particularly in the distinct "celeste" shade that has become its signature colour. Of dubious origins (some say inspired by the Milan sky, but most likely a product of surplus WWII paint), the exact formula of "celeste" has varied throughout the years. But it has always been some magical mix of sage green and powder blue - offset by the seductive shimmer of Campagnolo components.

As I stare at these images and sigh, I wonder what on earth attracts me to these bikes - Straight out racing bikes that two years ago I would not have even known how to mount, let alone ride.

Bianchieven produced several mixte models throughout the years - But somehow, it's the classic racing bikes that really draw me in.



And while initially my interest in Bianchi was purely aesthetic, that began to change as my cycling skills expanded. Over time,I have transitioned from thinking ofthese bicyclesas mere eye candy, to seeing myself riding one in future - most likely as my "wildcard" bike, to replace the vintage Trek currently occupying that spot.








[image via prollyisnotprobably]


One interesting industry development, is that the current Bianchi company is re-introducing lugged steel to its modern line-up as part of the Classica line. This began with the partly lugged Dolomiti roadbike in - greeted with some dismay due to its awkward mix of modern and classic features. The line up looks more promising, with the Tipo Corsa and the Pista Classica - both featuring chrome lugwork and fork crowns. Though the lugs look somewhat generic to me and the price is likely to be prohibitive, I am excited to see this and look forward to the models being released. Bianchi "celeste" is at its best when surrounded by lugwork, on a classic steel bike.

Look Once, Look Again...More Free Books

Here is the second set of books I have to give away. This is a set of "Look Once, Look Again" books. Again, these are hardcover with library bindings. I have a set of five of them: Mouths, Tails, Feathers and Fur, Leaves and Eyes. They are recommended for ages 4-8. You can take a peek at one of them here: Amazon
