Southern Utah boondocking: how long do roads take to dry?

We are hoping to get to southern Utah sometime later this year -- lots of boondocking available all over the place!

Just one problem: the dirt roads get very slick in wet weather -- the soil contains lots of bentonite, which is a clay that is so slippery that it is used as an industrial lubricant!

There are many warnings on the BLM and national forest websites that tell us to avoid certain roads in wet weather. Fair enough -- I've been warned.

But in general, how long do the roads stay wet after a rain? A day? A week? How does one know when it is safe to venture out into the back country?

Thanks in advance for your advice, especially if you have real-world experience with this issue!

  • Take a look at Yoo Toob channel Matt's Off Road Recovery for some sweet sw Utah mud action.
  • Bentonite is used as a drilling mud when drilling oil or gas wells. I worked my way thru college by working in the oil patch during the summers. While tying in a gas line to a newly completed well (gas lift well) we experienced a fire. Naturally we all ran in different directions. One of my coworkers got about 3 good strides into an old pit containing bentonite and cuttings from an old well. That pit was 5 or 6 years old. It had a 3 or 4 inch crust on top but under that the bentonite was just like the day it was put there. He sank in above his hips. That stuff is slick.
  • Doesn’t this depend on sun exposure, drainage, grade, tilt, crown etc.? Chugging along just great and whammy...sliding like crazy as you round the hill? I love Utah!
  • We ride our RZR in Utah and enjoy the wet roads. It seems the dirt roads can take longer than a week to dry, assuming it doesn't rain again.
