Where to Find Jasper in Nebraska

Nebraska jasper shares ground with the state's prairie agate and chalcedony. Sioux and Box Butte counties in the Pine Ridge country produce red, yellow, and brown jasper in Tertiary silica-cemented sediments, often with banded chalcedony rims. The Hat Creek and Indian Creek drainages in Sioux County yield surface jasper float on ranch country. Cheyenne County adds occasional dendritic jasper in the North Platte gravels. Nebraska jasper tends toward soft, earth-tone colors and modest size, but takes a good polish for cabbing. Most ground is private and access depends on ranch permission. The most productive ground is in Pine Ridge country (Sioux County), Hat Creek drainage (Sioux County), Box Butte County.

Casual hand collection of common rocks and minerals like jasper is allowed on most BLM and U.S. Forest Service land in Nebraska, with daily and annual limits set by the local field office. National parks, most state parks, and tribal land are off-limits. Always confirm rules before a trip.

Pine Ridge country (Sioux County) is the standout. Other strong ground includes Hat Creek drainage (Sioux County), Box Butte County.
