For fathers day we went on a complete circumnavigation of the Great Salt Lake.
This is about 400 miles of driving, about 1/3 of it on dirt. It took us about 12 hours, stopping a-lot to see stuff like the Salt Flats, the Sun Tunnels, The Golden Spike, The Spiral Jetty, and lots of wildlife.
There is, as usual, a small pond right where you leave the pavement. We skirted around this and then just drove.
I saw no signs of loose or wet patches. We drove out about 5 miles. Every indication is that the salt is of uniformly good quality. We did not see anyone else driving on the salt, but we saw some tracks. If the salt stays as it is or dries out more, then we will be in great shape for HellFire.
