Decades ago, b4 I was drafted (1st CAV), I worked for Weyerhaeuser out of Klamath Falls Oregon . A HS teacher on summer vacation was my "guide"! He got us to the W lands, I did the forestry work. The diameter of Crater Lake's rim is less than the diameter 20' - 30' below the rim. We jumped off the rim, landed on sand like earth and "skied" down to it in our boots. He knew a location where tree branches were lashed and/or nailed to living saplings and that was your ladder out! Anyway, you should check it out and enjoy. I did my "Advanced Infantry" training at Fort Lewis . I will tell you, the beer and babes in Seattle were fine, the few times they left us off the resignation! "Damn spell check!" reservation!
