Asx‘ée-L’ux, twisted-tree/milky water (Eagle & Herbert Rivers) meet below Glacier Highway, 28 miles north of Juneau (thumbnail, right). It’s an astoundingly productive and beautiful confluence.

I will always belong to the delta at Asx‘ée, the hundred-acre outpocketing of glacial sediment where I lived from 1980 to 1992, learning to draw and take notes, slowly becoming a naturalist. The map I made in 1983 is here.

According to Gul’guyéil (William Kunz), Asx‘ée was a L’eeneidí winter village of more than 50 people on land later claimed by the Boy Scouts. Since canoe access is challenging throughout the delta’s sand and mudflats, likeliest village site was on a raised, sandy bench just south of today’s Boy Scout lodge. The last of this loose deposit, covered with spruces less than a century old, was washed away by storm waves in the 1980s, shortly my arrival.

On a rare clear day in late October, 2015, with my 3DR Solo quadcopter, I ‘flew’ the flats just west of their confluence. Toward the end of this 1-minute video, you’ll see an anomalous-looking mowed-grass mound that also clearly shows on the preceding bare-earth map—remnant from the days when it was okay to mine gravel from the banks of our finest salmon streams. Bob Armstrong says at salmon time many bears fish here, apparently mostly at night. They also dig for roots—of which species we haven’t determined.
