Rare along Eagle Creek and increasing in abundance heading upslope on Ski Run Road. Saplings fairly common in Nogal Canyon and mature specimens frequent on slopes below Nogal Peak in the White Mountain Wilderness of the Lincoln National Forest. T10S R12E S 1/4 Sec. 35.

Although the velvet ash do occur in the canyon bottoms along creeks in this area, they are quite rare compared to their fairly common distribution on the slopes at higher elevations. Specimens at higher elevations were more shrub-like (multi-trunked and maximum of 20 feet in height) than tree-like while specimens in the canyon bottoms were always trees. All specimens noted at the time of seed collection had glabrous leaves. | 2139677 | Ames 35915 |
