The Pinyon CDF station was contacted on Monday and was first on scene. After appraising the situation the Riverside County Sheriff was notified and RMRU re-tasked from another rescue. RMRU members were preparing for a difficult winter rescue, not knowing the subjects conditions and noting the possible multiple carry outs. Multiple agencies were consulted and they determined that the best & safest method would be to plow the entire snow covered dirt road. A caterpillar was available for refueling the relay towers and it was commandeered by the Sheriffs Department for assistance. The Sheriff was also able to obtain a snow cat vehicle from San Bernardino in case of drifts. The caterpillar made it to the top of Toro peak but was stopped by huge drifts at the top. The caterpillar had taken four hours to reach Toro Peak. In about one hour the snow cat made it easily through the drifts passing the caterpillar all the way to the top camp ground with me, a USFS route finder and 2 fireman drivers from San Bernardino. On reaching the many subjects, all were examined and in remarkably good condition considering the circumstances. All were hastily driven down the mountain in nice warm vehicles. However I was forced once again to descend in the snow cat which is not designed for traveling over a bumpy, rutted, freshly plowed dirt road. The bumping and bouncing were so severe, they popped off my seat belt once, turned off my cell phone and made radio communication with base impossible.
