os1rfw, I put VERY LITTLE stock into what some of those compendium effort countries lists have. To give the background of how such *wonderful* lists get assembled, read on T'net, "treasure hunting legal issues" section, under the recent "California beaches" post. To just use that as an example, of they psychology of how such lists get compiled.
Ok, and what about them ? Not prohibited on those 2 types land in Utah. So long as you're not snooping around obvious sensitive monuments.
