The trip report: Krista Bartel, Martin Carmichael and I, spent the day Saturday working on the SkyCrapper. The goal was to place it up on bricks and attach the steps. It is now operational. Despite it being frozen to the ground, we figured it out. Our concern is that it will settle this spring so we made the steps self-supporting to prevent damaging them or the SkyCrapper. Many thanks to Krista and Martin for changing there “Fun” plans at the last minute to work on a shit house. read more

The normal annual bat census trip in Carroll Cave is run in late October. Last year (2019) the trip almost did not go due to lack of participation. We wound up doing a partial trip with only three people. That trip only went as far as the Lunch Room. We documented the state of the guano gauges but did not get to count any bats. read more
