About this location
Coalville is the Summit County seat, named — as it sounds — for the coal that was mined here starting in 1858 to supply Salt Lake City and Park City. That coal history is the town's real story; mindat's own locality record for Coalville, however, does list a small manganese-mineral suite alongside the coal: manganite, psilomelane, pyrolusite, and native sulfur. Mindat flags its own Coalville data as limited, and no source found ties these minerals to a specific mine, dump, or accessible spot — this reads as a broad, town-level locality pin rather than a documented collecting site. Worth knowing the minerals are real and recorded here; not worth planning a dedicated trip around without more specific information.
Always seek permission where required, follow local laws, and practice Leave No Trace. Locations and details are community-submitted and may be inaccurate. Not sure what's legal here? Read our full guide to rockhounding laws by land type.

Know before you go
Land status around Coalville is unverified — confirm ownership and permission before visiting. Summit County mixes private ranchland, some state trust land, and scattered BLM/Forest Service parcels; without a specific site name, it's not possible to say which applies here. Coalville's own coal-mining history (active roughly 1858–1972, with minor activity into the 1980s) involved private and company-owned claims, not public land.
