Jackpot’s center stands about 5,290 ft above sea level. Within three miles the land runs from 5,090 ft to 5,700 ft, a difference of 610 ft: hilly country. The highest named summit within 15 miles is Gollaher Mountain, about 8,130 ft, 14 miles east-southeast.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 8×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Rhyolite. Age: Middle Miocene to Late Miocene, 8 to 14 million years old. About 9 mi of the line.
Volcanic. Age: Miocene, 5.3 to 23 million years old. About 7 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 6 mi of the line.
Age: Miocene, 5.3 to 23 million years old. About 1 mi of the line.
Sedimentary, volcanic. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 0.9 mi of the line.

A raindrop that lands in Jackpot reaches the Pacific Ocean by way of Shoshone Creek, Salmon Falls Creek, the Snake and the Columbia: about 980 river miles.
Lakes on the way: Lake Umatilla, Brownlee Reservoir, Cove Arm Lake and Salmon Falls Creek Reservoir.
