NABSQNO 12S-668540-4325995. Jonathan Jones Arch is a cave natural arch eroded through sandstone of the Glen Canyon Group. It is located almost exactly on the state line between Utah and Colorado, above Jones Canyon, in a BLM wilderness area west of Grand Junction in Mesa County, Colorado. Access requires a permit and directions from the BLM ranger station in Grand Junction. The arch was named for a teacher in Grand Junction, not for the canyon it is in. It has a span of about 30 feet.
