This trip is for students of the Seattle Alpine Scrambling course only. This is an optional field trip. This is an opportunity to judge your level of conditioning; we recommend that students aim to be in sufficient shape by the end of May to be able to reach the bottom of the haystack with a 25 pound pack in under two hours thirty minutes. Due to limited space on this field trip, it is intended for students who are fairly new to hiking and to those who are concerned about their level of conditioning.
