More Trig Leveling

I have a project coming up in which I'll be doing pretty much the same thing, except I plan to use a TCRA1102 on one side and a T2000 on the other so we can get simultaneous reciprocal zenith angles. We'll do this across the Sacramento River in 3 places spaced about 3 km apart, connecting an existing Second Order Class II line on the east side to a new Second Order Class II line on the west. Crossing distances will be about 200 m at each site. Should be fun!

Everything's rising here- they issued flood advisories for the Flathead this week. Need the nights to stay cool for a couple more weeks.

The brass cap is for the gauging station but we're incorporating it into our control because it should last thoughout the duration of the project.

The west side was a rebar TBM, that we ran digital levels to from our primary control.
