The range is located to the east of the Ironwood Forest National Monument. Ragged Top, located in the north of the range, is a well-known landmark in this former mining region.

Description

The range is named after the Silver Bell Mine located at the southern end of the mountains. The range abuts the Waterman Mountains to the southeast, where palynology-(pollen) studies have shown some of the recent floristic history of Arizona during the Pliocene. Both ranges lie in the northeast Sonoran Desert; the Madrean Sky Island ranges begin just southeast of here, with the large, and most western sky island range, the Baboquivari Mountains-Quinlans 20-35 mi south.

The Silver Bell range can be accessed by Avra Valley Road and Silver Bell Road from the south of Marana.

Climate

Climate is characterized by extremely variable temperature conditions. The Köppen Climate Classification sub-type for this climate is "Bsh" (Mid-Latitude Steppe and Desert Climate).[2]

gollark: Ah, it looks like Planck's law is what the graph is showing.
gollark: > If you make the temperature higher, then the frequency increases. No, you keep ignoring me on this.> Thus meaning the amount of photons emited is related/proportional to the temperature increasing.Also no, the amount is a different thing.
gollark: Also wrong, objects emit multiple frequencies at once and the relationship is more complex than that.
gollark: The energy is a property of the photon similarly to frequency and stuff, the energy doesn't have frequency either, but can I just say that trying to brute-force your way to coherent-sounding wording is not a path to great understanding.
gollark: Why does the energy have a wavelength now?
