Saturday - January 29, 2005 - The annual bat count at Alabaster Caverns State Park. Each year a census of the bats that hibernate in the state park is taken by the park's Naturalist Mike Caywood. With the help of volunteers from the Park's Venture Cave & Rescue Group and the volunteers from the Selman Bat Cave tours, this years bat count was started.

For most of us who work the Selman Bat Cave Watch Tours in the summer...this was a different picture! | We usually almost die of heatstroke in the middle of the summer but an 8 in. snow changed the scenery. | Wow Mel....good thing you stayed safe at home!!!...the snow came all the way up to the roadway!! |

Something to remember... the walkway filled with snow! Wow! Different indeed! | Today was the first day of tours after the collapse at the main entrance. One boulder off to the side shows what it was like! | Those roots USED to be on TOP of rocks! New face on the entrance for sure! But it is safe again...come on and try a tour!! |

This is what it is all about. This is a common cave bat (myotis velifer). They sleep the winter away (hibernate) here in Alabaster Caverns. | They go to sleep in cold caves. While asleep, their grips tighten (while we relax) and they can just hang there. | The cave was approx. 43 degrees F. These myotis are single sleepers while others sleep in giant mats. |

The cave was recently redone with new lighting. Here shows the new handrails which are lighted underneath. | A mat of myotis. If you can find a big enough mat, you can determine a packing density. A 1' by 1' square is determined and by math you can tell how many are in a square foot. | Our packing density was 244 bats per square foot. By taking measurements of how long and wide a mat is you can determine how many bats are in a mat. |

Fingers next to the bats show you the actual size of the bats. A common myotis is about the size of your thumb. Its wingspan is almost 4 times that! | The bats can find any nook or cranny to sleep in so the counters have to probe in every crevice and passage to find them. | There were two other bats hanging out (not these)... Pips (pipistrellus subflavus) and Big Browns (Eptesicus fuscus) (see picture later for Big Browns) |

Park Naturalist Mike Caywood uses a digital thermometer and checks the temperature of the rock and the bats. | One of the largest mats in the cave. They were really bunched together here!! | During the bat count, counters call out numbers of bats and the recorder writes down the numbers in a book along with stats of temps of rock and air. |

We had quite a crew for this count so no bat was left uncounted (we hope!) | Everyone has to wear helmets and a hands free light source. Helmets for that stupid ceiling that just lowers on your head for no reason and hands free to maneuver off trail. | A pair of Big Browns (Eptesicus fuscus).... the only two we could find, weggied into an itty bitty crack in the ceiling. |

The Alabaster Caverns Bat Count Crew 2005. | Oh...yeah... after we finished the count, THEN Mike told us we didn't have a tram to take us back! Notice the down trodden folks after the news! | After 1,230.34 miles of snow covered brutal sun blinding hiking miles, the crew finally gets back to civilization. |
