Many nations of the northern plains hold this rock sacred and have their own names for it. The Lakota Mato Tipila, Bear Lodge, is the one most often used in English; Cheyenne, Kiowa, Arapaho and others have theirs. Several tell versions of a story in which the rock rose to lift children out of a bear's reach, and the flutes down its sides are where the claws went. It became the first national monument of the United States in 1906, under a name that appears to have entered the record through a nineteenth-century mistranslation, and which the nations concerned have asked without success to have changed.
Two uses of the same rock
Recreational climbing grew through the twentieth century on a formation where people come to pray, and the collision was sharpest in June, when many though not all of the ceremonies fall.
The Park Service's climbing management plan of 1995 answered it with a voluntary closure for that month rather than a ban, worked out by a group that included both climbers and tribal representatives. A climbing organisation challenged the plan. The voluntary closure survived, the Tenth Circuit ruling in Bear Lodge Multiple Use Association v. Babbitt in 2000.
Thirty years on, the Park Service reports a significant reduction in June climbing, and the Access Fund, the national climbing advocacy body, endorses the closure and the wider plan.
The awkward lesson
Devils Tower is cited constantly as proof that sacred-site accommodation can work, and it is. But the reason it works is worth being honest about. It works because it is voluntary. A request raises no establishment-clause problem, so it survives challenge; a requirement would face the objection that the government was managing public land for the benefit of a religion. The accommodation is durable precisely to the extent that it is unenforceable, and it holds because climbers have chosen to honour it.
Every attempt to give a sacred site mandatory protection of comparable strength, at the San Francisco Peaks, at Oak Flat, has failed in court. That is the pattern, and Devils Tower is the exception that shows why.
