In 1875 he opened a general mercantile to serve the miners east of the Missouri River at Cavetown. He moved to nearby Canyon Ferry in 1880, and by 1883 had established a general store and later added a livery stable and two-and-a-half-story hotel.

FAQ
How do I get a reservation at Court Sheriff Campground?
Campsite Sniper's current snapshot shows none of the 135 tracked site-nights open for online reservation at Court Sheriff Campground. That can mean dates are reserved, closed, not yet released, or offered first-come, first-served rather than online. Campsite Sniper has also detected 3 site openings here in the last 90 days, so further dates may appear. Pick a site on the map to see its calendar, or set a free Campsite Sniper alert. You complete the reservation yourself on Recreation.gov.
Does Campsite Sniper book this campground for me?
No. Campsite Sniper sends alerts and direct Recreation.gov links. It never books, pays for, holds, hoards, or resells reservations.
How current is this availability data?
Campsite Sniper re-checks public Recreation.gov availability for this facility every hour and republishes whenever anything changes. This facility's data last changed at Nov 2, 2026 18:20 UTC; an older timestamp means nothing has changed since that time, not that checking stopped. Always confirm final availability on Recreation.gov when you book.
How often do new openings appear at Court Sheriff Campground?
Campsite Sniper detected 3 site-date openings here over the last 90 days, none in the last 7. A free alert watches around the clock and pings you the moment one appears.
Which sites at Court Sheriff Campground fit a 35-foot RV?
38 of the 45 sites that support RV analysis have a recorded maximum of 35 ft or more; the longest recorded is 100 ft. 41 of those 45 sites have a recorded maximum length and 4 do not; they are not counted as fitting.
When is the next open date at Court Sheriff Campground?
Campsite Sniper cannot answer that from the current snapshot. The availability data held for Court Sheriff Campground begins May 1, 2027 — about 180 days after this snapshot was taken, so any earlier dates are outside what Campsite Sniper is tracking here rather than known to be unavailable. Check Recreation.gov for dates before May 1, 2027.
