Over the Memorial Day weekend, eight California cavers visited the karst in the Marble Mountain Wilderness in northern California. This area has the deepest and second-longest cave system in the state (Bigfoot), along with dozens of other caves. The caves are at altitudes ranging from roughly 5500 to 6600 feet, with ambient temperatures typically 35-37°F; many are also fairly wet, so proper attire is a must for safe caving.
Four of the cavers were wearing the Salamander Caving Suit; this is a lighter suit than people usually use in these caves, but they worked wonderfully, with most people wearing one or two layers of polypro and/or fleece underneath. In one cave, one caver even made use of the convertible sleeves after realizing he was working up a sweat despite the chilly temperature!
On a hike around the karst prior to caving on the last day, a couple of the cavers also found the "hiking-pants-only" mode to work quite well, especially when bushwhacking through heavier brush (not to mention the fact that it's easier to carry your suit by wearing it than by stuffing it in your cave pack).
