signs, everywhere signs. The no potable water at the Chalet is also posted on the Highline Trail but I think maybe it's not posted in the best spots. The Iceberg/Ptarmigan Tunnel had been closed since Saturday. It was at least ten days before the trails were re-opened. Also in LR, notice the old CDT sign.... not that you would know that. I didn't but Wendy pointed it out. And of course in the LL photo she is pointing at where we were the last two nites.
