CLUI: Day Fourteen

collapsed canal backfill, South Base playa, Utah, April 2010

Flat Light. Cycling perhaps ten, twelve miles out. Parallel with the huge trenches of the salt/potash mining, eventually towards Blue Lake. A bit nervous about unexploded ordnance, but there are plenty of old vehicle tracks in the playa to follow. The berms, canals, and drainage engineering has completely off-balanced the system here. In its original condition, as it still the case north of I-80, there is a thick layer of very hard and relatively pure salt overlying the extremely fine-grained mud that accumulates as the ranges surrounding the playa slowly erode. It’s this same very fine-grained sediment that comprises the nasty dust in the frequent and rather violent wind storms kicks up high into the atmosphere. When wet it becomes a gooey mess that is at the same time, slick and very dense. The very reason that it costs USD 600 if you get your vehicle stuck somewhere in the local playa — usually when the salt ‘ice’ breaks through — it takes a snow-cat to tow it out. And, as the basins between the ranges are being formed as a result of wide-scale extensional tectonics, that stuff is deep, thousands of feet deep! Nothing like the feeling of being out in the back country here with a vehicle that is stuck or has broken down. Cell phones usually don’t work, and it’s a long walk anywhere. I carry plenty of water (10 gallons), a shovel, tow cable, full tool kit, flash-Lights, some food, sleeping gear, signaling mirror, and other bits of paraphernalia to at least make it a comfortable wait. And most of the time, I have my mountain bike which would make a 50-mile exit a possibility.
