Ponderosa Canyon is named for the huge Ponderosa Pines 
Ýview on the Canyon floor. Some of these trees measure more than five feet in diameter and exceed heights of 150 feet. Yet from the viewpoint it is difficult to determine the extreme height of this forest. Also from this vantage point, visitors can see the types of rock that compose the graduated steps of the Grand Staircase. In the smooth sandstone of the White Cliffs, the soil is thin and plants cannot easily grow. This lack of plant life causes the region to endure intense erosion with each rainstorm — forming steep canyons, and rounded domes. At Ponderosa Point, Blue Spruce, Douglas-fir, and White fir comprise a Spruce-Fir forest for visitors to explore.  260 220 2 84
