We went last fall while on a circular trip from Colorado to Waterton Lakes, Glacier NP, Craters of the Moon and finally Arches NP before we headed back home to Colorado. We were told about it by somebody at the hotel where we were staying and decided to take a look late one afternoon. We were given a map which was very helpful because without it we would never have found it. The drive is mostly on dirt roads and it feels like it is out in the middle of nowhere, which in a sense I suppose it is. There was nobody there the hour or so we were there which was OK with us. We didn't see anything spectacular while we were there but were able to get some good photos of the patterns the water makes in the minerals as well as some very interesting colors. Also, some of the rock formations in the area were pretty spectacular to a non-geologist like me. This was a nice respite and change of pace from all the driving and 'touristing" we had been doing.
