We spent the day practicing cave search, horizontal movement, and vertical rescue techniques. We have found that radios work well in Southern California boulder-talus caves. The litter shield designed by Paul Stovall for use on the OSS works well too. A dropped radio bounced off the patient's face without incident...to the patient. There are a variety of skylights in a boulder-talus cave that may be suitable for evacuation, but it is often difficult to assess them from the top or bottom exclusively. We put an avalance transceiver on each search team to be activated in the event that they found the patient. This was then used to attempt to pinpoint their location from the surface. Amazingly, it worked rather well. This will warrent further study.
