The month of April had us visiting a frequent port of call – Mt Rainier National Park. The climbing ranger cadre at Rainier responds to similar missions as the Denali NPS rangers – crevasse falls, hypothermia, altitude illness, and the myriad of others means of being incapacitated in the high mountain alpine environment. We worked on some of the rigging/rescue basics as per usual, but then stepped into some more advanced techniques for moving rescuers and patients in high consequence ground. The team executed a Kootenay Highline System with the English Reeve variation over a narrow gorge. The English Reeve is an elegant aerial ropeway suspension system that can control the live load in two planes.
