"Returning to the unexplained stone cairns in the Pacific Northwest, Frederica de Laguna (1971:82) in her amplified edition of George Thornton Emmons' The Tlingit Indians: provides the following details:
More baffling than petroglyphs and stone carvings are cairns of piled stones to be found on the mountains well above timberline, both on the mainland and on offshore islands. They have no relation to the Russian occupation, and are not boundary marks. They are away from any trails or lines of travel, at altitudes of from two to three thousand feet, located on clear stretches, generally on mountain tops. The oldest natives can give no explanation of them, beyond the story that when the great Flood covered the earth, those who survived in canoes floated up and moored their craft here with great bark ropes, the decayed ends of which it is claimed can still be seen. [Cairns like these were said by the Tlingit of Angoon and Yakutat to be "nests" or forts made by survivors of the Flood to protect themselves from the bears that were driven to the summits of mountains by the rising waters (de Laguna and McClellan, field notes, 1950, 1952). Stone piles have been noted by some members of the U.S. Geological Survey, who offered no explanation for them. My archaeological party of 1935 explored a pile of stones on a high ridge above the middle Yukon River, between Nulato and Holy Cross; this "cairn" was due to frost action, according to our geologist, Jack Eardley. But this explanation may not apply to all such piles.] The following locations of such cairns are known, others may still be discovered: On a mountain 2,500 feet high, above Union Bay and Ernest Sound, on Cleveland Peninsula, there are four or five pyramidal or circular piles of stones. Watson, half-breed, knows about this. On a mountain on Etolin Island is a cairn of boulders. At Gambler Bay, on Admiralty Island, on..."
