[Geysers] Geyser Report Tuesday, September 11, 2012

[Barbara Lasseter]

45 degrees this AM in West Yellowstone as I headed for the park 0545.
The temps dropped all the way in, reaching 34 degrees on arrival at
OF.  Once the sun cleared the ridge, it began to warm, and near mid
day the smoke blew in.   That 16 degree prediction had been revised
yesterday, and in fact the day was quite mild. I spent most of the AM
at Lone Pine, which was overflowing and boiling when I arrived at
0810--and when I left at 1100.

The prediction for Grand geyser is now 5-7hours--a 2 hr window and a
6hr interval.  The eruptions I've seen continue to occur in the first
hour of that window.

We seem to have more motor homes and RV's in the park than ever.  At
the same time, fewer appear to be rentals.  Must be part of the after
Labor Day shift in visitors to more retirees.
