We shared our campsite at Columbine Lk. on Sunday night/Mon. morning. Had great interaction and discussions about lightweight travel. I suggested to Steve that he go down the Big Arroyo rather than take the alternate route to Rattlesnake Ck. I told him I have gone down the Big Arroyo before and that he should have no problem in this low water year. I believe his Spot is working as it should and that he is proceeding down the BA today and will have more time for the Kern Hot Spring along his trek. He is a very capable hiker who should have no problem with that route.
