              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started with snow drifts on the roof and some impressive ice sheets hanging off the edge of the dome. There was water dropping off the roof when I walked on the catwalk. Things were too dangerous to open tonight so, even though the night was clear, we remained closed.
No Problems tonight.
The dome is parked west in hopes of some sun melting the ice during the day.
