Getting to GRIP with it

Today I went to GRIP to inspect the casing of the borehole there. It's always a popular destination, and this time I brought 7 other folks from camp- they were happy to get out and about!

Logging the GRIP borehole to inspect the casing.

I'll post the results of the survey later when I've processed the video, but the first look indicates that the casing is completely intact, with none of the buckling we saw in the GISP2 borehole. The survey was cut short by a plug of ice which has formed about at the fluid level, and which in past seasons we'd had to break through with a heavy weight. The plug looked pretty solid! Pictures of it soon.
