Ellen McCallie's Diary

Day 28: Altimeter

Photo: Kate, Ellen and Jonathan with the altimeterRaining, raining, raining, raining. All last night. Off and on all day. Actually it was quite warm — or it felt so with the four layers I'm wearing. In terms of science content and filming, the day was very pleasant. Jonathan and I made the altimeter at the sawmill, took it to the river bed below Sentinel Point and sealed one end of the tubing. We carried it to the top of Sentinel Rock to get a calibration reading for a 40 to 50m change in elevation. We then checked to make sure the metal detector Jonathan made in a previous programme was still working.

In between times, we made tea. Brits do like their tea, particularly with milk!

I helped Mike L. smash up rocks. I asked if I could help Kathy with the gold but everything was pretty much under control. The bad part is that several people are under the weather.
