Am planning a north-bound thru for SNP next week and want to know if anyone has recent experience regarding the water sources at Calf Mountain and Black Rock shelters. I would hope that recent rains would have those two springs running fairly well. Info on SNP website dates back to Sept. 2016. And water is heavy!

Also, I understand that food vaults have been installed at shelter sites beginning at the north end of SNP.
About how far south (shelter-wise) have the vaults been installed?

Any other recent observations would be appreciated. Thanks.
