There is a belt of nearly empty land in northern Arizona called the Strip (not to be confused with the far more commercialized one a bit to the north, in Nevada). Running from the southeastern Utah border, it spans the space between Utah to the north and the Grand Canyon to the south. Few paved roads traverse it, though it is riddled with four-wheel-drive routes and gravel roads that verge on four-wheel-drive. With my brother, I ventured from St. George, Utah into the Strip in mid-October, 2016. The journey ultimately claimed a car tire (via a slow leak that took multiple efforts to diagnose, a leak that ran like a vein across many future outings, including a grand venture to the Grand Canyon, North Rim) but provided both a rigorous hike (that ended most precipitously in a steep descent down a scree slope covered in thorny and spiky desert plants, when the trail vanished and left us stranded quite a few hundred feet above and a mile away from our car). On the way back home, just shy of the Utah line, we visited a petroglyph site. Little Black Mountain, situated on BLM land, encompasses a number of boulders etched with various images and designs strewn along the bottom of a small mesa; some of the petroglyphs there date back 6,000 years. In case you find yourself on the Arizona Strip someday (or lodging in St. George and having a spare tire in your car), here is a link to further information about the site: https://www.blm.gov/az/st/en/prog/cultural/lil-blk-mtn.html.
