The mountain is heating up today! Here's the latest report from the observation post at the crater:

"Atmospheric conditions this morning are helping produce a strong steam plume that is rising above the volcano. Rockfalls from the dome continue and cause occasional plumes of ash, some of which rise above the rim. As the dome grows, such events are to be expected. When valley fog clears sufficiently, a crew will head out to measure volcanic gases. A GPS package on the bulging east arm of the glacier continues its rapid (4 feet per day) trek northward."
