Variation in annual precipitation within Red Butte Canyon is strongly dependent on elevation (Figure 7). The slope of this relationship is similar to that observed for other mountainous areas within the Great Basin (Houghton 1969), and precipitation at the Salt Lake City reporting station (Salt Lake City International Airport) falls on this relationship. Thus, while lacking continuous precipitation records available for Salt Lake City can be used as a preliminary basis for estimating mean annual precipitation at different locations within the canyon.
