Here is a currently working map sub-link for St. Helens boundaries.

Giant rock growing in Mount St. Helens' crater

The large rock 'fin' continues to grow nearly 6 feet per day, although some breakup & rockfalls continue from the lava protrusion.
This first link is to KGW TV News out of Portland & their most recent story containing photos & comments from USGS geologists.

This second link is the volcano cam where you can see the fin within the crater. Although from the camera's perspective the fin appears ready to top the crater's rim, it is in fact many hundreds of feet below it.

This concludes this irregularly scheduled update.

The view is a bit obscured just now from the Johnston Ridge Volcano Cam, but it appears the fin is still intact. Steaming away currently & laying in a shadow of clouds, the somber mountain has quickend the quake activity lately & continued to amaze & surprise ameteur & professional alike.

OPB, our local PBS affiliate ran a special on Cascades volcanos last night; Oregon Field Guide : Cascade Volcanoes. Predicting volcanic eruptions in the Cascades. It airs on OPB again Sunday, May 28, 2:30am & 6:30pm.
One of the geologist commented the most difficult thing for people to realize is that the mountain is continuously errupting now. From the first quakes & emmisions in October 2005 to present, lava continues to extrude. One puzzling factor is how de-gassed the lava is. Not explosive like 1980, but not runny either as in Hawaii.
This seismogram link is the nearest Mt. St. Helens station to me; I'll check GPS for exact. Activity is up & weather is foul. Whether the new fin is intact or not still is anybodies guess.

Checked GPS;39 miles between the Cedar Flats seismometer & me. All of the above conditions apply today as well & here is current seismogram. Yeah I'm twitchin'!

When weather clearing permits flyins we can expect new reports on the 'fin' structure.

I just checked the image and it looks like the volcano has blown up. Its all smokey! haha.

Breaking News:2:03 PM Pacific Daylight Savings Time: The fin has collapsed this morning either causing or as a result of a 3.1 quake 2 miles beneath the mountain. A large ash plume rose over 17,000 feet & drifted NE. First link is KGW TV web news out of Portland Oregon & second link is the seismogram display for the time period of the event.

The weather cleared enough today to allow helicopters in for a survey of the crater after yesterday's 3.1 quake. Hot ejected ash & rock has landed on the glaciers & is producing the first notable glacier melting since the eruption started last October.
The first link is the USGS Official update for today, & the second is the Portland TV station KGW website. Registration is required to see their video, but the piece I noted that is on their front page is 5 minutes of raw helicopter video from inside the crater TODAY. Very worthwhile.

Cloudy weather has the mountain obscured & quakes have increased over the last several days. We had a 3.2 on the mountain last night & I heard some reports of an ash/steam plume rising above 10,000 feet. I haven't verified the plume report, but here is the quake report from USGS:
http://earthquake.usgs.gov/eqcenter/...uw06100404.php
In any case, a 3.2 is sufficient to knock down parts of the growing fin. The viscous lava fin continues to grow around 6 feet in altitude per day.

I discoverd that if I climb out onto my roof & up to the peak of the garage I can see Mt. St. Helens!
