The sources’ own words
bigtooth aspen (reddish orange)
A medium-sized tree that is common in disturbed areas and roadsides. Its alternate coarsely toothed leaves turn yellow (and occasionally reddish) in mid-October.
Although bigtooth aspen can grow at sea level and has been found at altitudes over 915 m (3,000 ft) in North Carolina, it is most abundant and develops best on flat to gently rolling terrain of floodplains or lower slopes of the uplands between 150 to 610 m (500 to 2,000 ft) in altitude.
Big-tooth aspen (fig. 1) is native to northeastern and north-central United States and southeastern Canada.
It is most abundant on sands, loamy sands, and light sandy loams, but it is found as a single tree or minor stand component on any soil, from rock outcrops to heavy clays.
Thin, gray, olive-green to milky green and smooth on young stems; later gray-brown, ridged with diamond shaped lenticels and splits forming.
