Populus tremuloides is a deciduous tree native to cooler areas of North America, one of several species referred to by the common name aspen.It is commonly called quaking aspen, [2] [3] [4] trembling aspen, [2] [3] American aspen, [3] mountain or golden aspen, [5] trembling poplar, [5] white poplar, [5] and popple, [5] as well as others.

They are all medium-sized deciduous trees reaching 15–30 m (50–100 ft) tall. In North America, the aspen is referred to as quaking aspen or trembling aspen because the leaves "quake" or tremble in the wind. This is due to their flattened petioles which reduce aerodynamic drag on the trunk and branches. Aspen trees near Crested Butte, Colorado
The bark is pale greenish-grey and smooth on young trees with dark grey diamond-shaped lenticels, becoming dark grey and fissured on older trees. [ citation needed ] The adult leaves , produced on branches of mature trees, are nearly round, slightly wider than long, 2–8 cm (1–3 in) diameter, with a coarsely toothed margin and a laterally ...
A male clonal organism, Pando has an estimated 47,000 stems (ramets) that appear to be individual trees but are not, because those stems are connected by a root system that spans 42.8 ha (106 acres). Pando is the largest tree by weight and landmass and the largest known aspen clone.

The forcing of the spring to the surface can be the result of a confined aquifer in which the recharge area of the spring water table rests at a higher elevation than that of the outlet. Spring water forced to the surface by elevated sources are artesian wells. This is possible even if the outlet is in the form of a 300-foot-deep (91 m) cave.
Leaf of Populus grandidentata or "big-tooth aspen". Bigtooth aspens are dioecious, medium-sized deciduous trees with straight trunks and gently ascending branches.Heights at maturity are around 60–80 feet (18–24 m) with diameters of 8–10 inches (20–25 cm).
Because the deformity is likely genetic and aspens propagate by root suckers, it is likely that all the crooked trees in the grove are clones that originated from a single mutated tree. The grove is currently bounded on all sides by the grid road and a perimeter access road, so the size of the grove is static and is unlikely to continue spreading.
