2021-07-12 Guano Pile Check

Guano pile quick check

Participants – Bill Gee
Rita Worden
Seth Colston

Time in – 8:00am, Time out 11:00am

For many years we have assumed that Carroll Cave was a summer host to a maternity colony of grey bats. The bats use several guano piles located in Carroll Passage upstream from the Lunch Room. We have done trips through there in October for about 15 years. The guano gauges always show signs of use at sometime in the previous year. We have never had any more accurate idea of when the bats are roosting over the guano piles. read more

2021-07-11 Upstream Thunder River to Mapped End

Participants – Bill Gee
Seth Colston
John Roth
Martin Carmichael
Hou Zhong
Rita Worden

Time in 9:15am, Time out 5:20pm

The weather situation for this trip was very dicey. We did not know what we were going to do until we got into the cave. The forecast for the night before the trip was for 1 to 2 inches of rain. Some rain did fall, but it was only 0.15 inches which is not enough to seriously affect the stream level. The daytime forecast called for showers after lunch. A shower did indeed happen, but less than 0.10 inch. read more

In October 2020 during the annual bat census trip, we placed a bat roost logger in the Mountain Room. The main goal of this trip was to retrieve the memory card for analysis. We also installed new batteries in the roost logger, added some stuff to the Mountain Room rescue cache and searched for evidence of bats in an upper level passage. read more

Areas visited – Carroll Passage to the Mountain Room

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
