I work on the Santa Fe NF Pecos/ Las Vegas RD, In NM Most of the first time guys that apply for the South West Firefighting crew will have to take a Rookie class called S-130,S-190, for like 5 days then take a test its not hard, then after you pass the test you'll have to take a Work Capacity Test which is a pack test. The pack test consist of walking with a Pack test vest that is 45 lbs. under 46 min. 15 sec. There is a great web site that you can go to just type USFS and it will let you in to all the Forest service web sites. Oh good luck and welcome aboard.
