I'm watching the streaming web cam and I see a lot of very unconcerned looking bison.
Re: Snow melt. This keeps coming up and I just don't think we have enough info to make anything of the level of snow melt on the web cam. How long has it been since it snowed? Even if the air is very cold the steam/warm ground will melt the snow (normal for the Old Faithful area) and will melt more over time.
It seems to me this issue comes up here cyclically. More snow falls, it stops falling, then it melts, then people worry about snow melt. I mean, it couldbe an issue, but unless we are there with our own gauges, observing the locations in question, how much snow they got, how quickly it melted, and how this relates to historical trends at that location - I kinda think it's a big nothing.

Hi Folks, I have just recieved this reply from USGS with regard to the downtime of LKWY.
.... SNIP .....
All,
A few more relevant points.
LKWY is not in a borehole. It is at the surface. It is part of the "backbone system" of USGS seismic stations that cover the entire country. It runs off a satellite dish, in contrast with most of the other seismic stations at YNP.
There is a nearby borehole with a strainmeter. That is different.
The borehole instrumentation also goes down due to telemetry issues, power problems, etc. A nearby GPS receiver is also called LKWY. It is now maintained by UNAVCO, a non-profit company that is a contractor to NSF.
LKWY was fixed by a park staff member who went out and cleared snow and ice out of the satellite dish.
A UNAVCO engineer was just out fixing problems with the strainmeters. Getting someone from Boulder out to the equipment requires a lot of time and money. Weather has been horrible. All travel is by snow machine.
Equipment goes down and comes up all the time. The equipment is run by different groups such as UU, USGS Denver, USGS Menlo Park, NSF through the UNAVCO consortium, the USGS Water Resources group in Montana, and others. If we tried to provide a running commentary on each piece of instrument that is up or down, it would be a major task
for us and those enthusiastic citizens pasted to their web browsers
would probably not be any happier.
Basically, the UU has had no problem locating earthquakes throughout the past few weeks, even when instruments go up and down. As you've noticed, big earthquakes (> M2.5) are located instantly by an automatic routine. Small ones take a few days to make it into the catalog, especially when staffing is low during the holidays.
My two cents.

I am also aware of the EQ clouds. I witnessed these formations 2 days before the 8-15-2007 8.0 EQ off the coast of Peru. I was standing outside and I said to my husband that those are the weirdest clouds I have ever seen. Unfortunately I didn't take a picture at the time because I was not aware then of their significance. It happened again, and I took a picture before the 7.2 EQ on 9-2-07 off the Santa Cruz islands. I know what I was seeing was truly EQ clouds, and I told my husband that there could be another another EQ since I saw those clouds, sure enough, the next day. I will post the photo later, I don't have my camera at work with me. I would love to see your photos so we can compare.
These are some more links to photos of EQ clouds

I looked at the photos in the link you provided, no the clouds are not the same. I am uploading 2 videos I took Monday to youtube right now. I will post them here, once they have been uploaded and are available.
The videos show waves.

David,
You are most welcome. We are always happy to answer questions from the public. I do look at the blogs on occasion and am struck how so many people would prefer to speculate wildly and figure it out by themselves, rather than by simply asking us and finding out the answer. We cannot take the time to explain every wiggle on a hydrograph or webicorder, but we could help people figure out snowmobile and wind noise compared with harmonic tremor!
And we are all scientists trained to do science. This is pretty much the ideal job for most volcanologists because we get to do what we love. We don't take any courses in "government secrecy protocols."
Actually, I'd be curious if they are offered:-). Nobody else in the government tells us what to do. We are the same folks who monitor the volcanoes in Hawaii, Alaska and the Cascades, and if we acted any differently for Yellowstone we'd lose our credibility everywhere else.

Hi Jake,
Yes you are right you would lose your credibility. Actually, apart from the obvious 'nuts' on the site, most of the guys and gals on this particular thread are getting very technical with the seismograph recordings and beginning to recognise more and more.
I would not want to take up your valuable time unnecessarily, but an explanation of the snowmobile and wind noise signals, and how to recognise them, would I am sure be much appreciated, and would lead to less wild speculation (although wild speculation on a conspiracy site has to be expected and can be quite fun as long as no one takes it seriously).
Perhaps, if someone has time, a web page explaining the difference may be the answer?
Thanking you once again
Best regards
David
