Exploratory trip via Rampart Lakes "Backdoor" 

The 1st portion of this trip will use the ski trail I cut to approach Mt Margaret , but then follow road 4832-136 to the Rampart Lakes Backdoor trailhead.   I have hiked the "Backdoor" trail several times, but never ski toured it.   The climb to Lake Lillan is quite steep, with significant exposure to avalanche terrain.

 If conditions aren't favorable, we can divert to a lower risk route on Mt Margaret. 

Last year's trips  were highly popular,  frequently having as many people on the waitlist as on the roster.    In order to distribute places on the roster more equitably than the "first come, first served" sign up model,  I'm trying a "weighted lottery" approach.    I've made the trip "Leader Permission Required" -- so when you request permission please provide the following information, which I will use for assigning "points" in the weighted lottery:

1) You are a current Mountaineer's member that meets the minimum requirements to participate -- 1 point.
2) Whether you will be fully vacinated for COVID-19 by the trip date -- 1 point.
3) If you have a Wilderness First Badge or other first aid competency (e.g. you are an EMT, MD, LPN, or other medical professional) and are willing to use your skills if  necessary on the trip -- 1 point.

Folks qualified as ski trip leaders and willing to act in that capacity as a co-leader will be accepted without using the lottery.

Note:  A Winter Storm Warning, Extreme Avalanche Forecast from NWAC, Freezing Rain or "Chains Required" on the highway will cancel the trip.    If NWAC forecast is for a High avalanche hazard -- a lower risk destination in the area will be selected.
