Ask about this camp →U.S. Forest Service lists this site. On most of their ground you can camp away from developed sites pretty much anywhere — so treat this as a known-good spot, not the only one allowed. The unit sets stay limits and how far off road and water you must be. What changes is conditions — roads, gates, closures, fire rules. Check those with the unit before you commit to the drive.
Nearest road on the Forest Service MVUM — Harkness Lake · Beaverhead-Deerlodge National Forest · MT
No road within 1 mi of the pin in the national MVUM layer — and that layer carries no data at all for this forest (unit 0102), so this is the layer's silence, not the ground's. Access may be a county road or unmapped.
From the Forest Service's own Motor Vehicle Use Map roads layer (EDW, Clearinghouse refresh Aug 30, 2026), straight-line from the pin to the nearest mapped segment. The nearest segment is not necessarily the way in, a maintenance level is the agency's class and not a report on today, and a road's season is the road's — it is not a campground order.

Coming out here — Harkness Lake · Beaverhead-Deerlodge National Forest · MT
- Surface water mapped nearby: USGS maps Tendoy Creek as a perennial stream, under 0.1 mi from the pin (National Hydrography Dataset, data refreshed October 2022). Mapped as perennial is not the same as flowing today. Nobody has checked it for you. Filter or boil anything you drink.
- Ground slope around the pin: about 33.7% — steep. Measured on USGS's 3DEP elevation model (1 m data here), sampled every 10 metres around the point. That is the hillside, not the ground under your wheels — a graded pullout or a bench a few metres across is too small to show up at that spacing, and nobody has checked this one for you.
- The game's day in this forest These lines are for the whole Beaverhead-Deerlodge National Forest, not for this camp's own spot: a fire restriction is posted by county, and a forecast is for one point in the forest. A camp's own night can differ from that point, most in the mountains. Read when this page loads from the same daily files the game uses; every line says where it came from and when it was read.
- This camp's own spot: sun and fire record Worked out for this camp's recorded point from federal records, not for the whole forest. Every line says where it came from and when.
Sun behind the west ridge: (USGS 3DEP elevation, bare ground, 30-meter steps, finer close to camp; trees not counted; worked out October 15, 2026 for the 15th of each month, in this forest's clock; nobody has stood on it for this.)
- No rail line and no interstate or US route is mapped within 10 mi of the pin. Checked against the FRA/BTS North American Rail Network (data updated Jul 21, 2026) and the Census's TIGER/Line primary roads (TIGER/Line 2025, released Oct 2025). Both are national files and both are maps of what is built, not counts of what moves on it.
- Assume no services at all. Most dispersed camping in a national forest has none: no tap, no power, no dump, often no toilet. Everything you need, you bring.
- Power: Dave carries his own — batteries or solar. A generator will run your rig and it is also the thing everybody camped near you can hear.
- Getting online: Dave recommends Starlink. He has had it since SpaceX introduced it, used it for four years living on the road, and it delivers as promised — several hundred nights out, and he can count on one hand the places he could not connect. The cable on his unit runs 150 feet, which is usually all it takes to find enough sky. Starlink → Referral link — Starlink pays Dave $100 in cash if you sign up through it, and that money funds this site and the next trip. It costs you nothing and does not change the recommendation.

The unit that manages Harkness Lake
Stay limits, road closures and fire restrictions at Harkness Lake are set by Beaverhead-Deerlodge National Forest, not by the campsite — check there before you go.
Snow, and when this opens
The nearest automatic snow station is Beagle Springs at 8,880 ft, about 3 miles away. It sits about 1,004 ft higher than this camp, so treat it as a guide rather than a reading for this spot. We do not repeat a depth here, because any number we stored would be stale by the time you read it — the station publishes today's.

Confidence
Likely — The record is good enough to put a pin on, but thin in places. Treat the details as a starting point, not gospel.
How it was placed
USFS/BLM authoritative: free & dispersed. Access not field-checked (assumed drive-up).
Nearest MVUM road
US Forest Service Motor Vehicle Use Map roads layer (EDW_MVUM_01, layer 1), Clearinghouse refresh Aug 30, 2026. Straight-line distance from the pin to the nearest mapped segment within 1 mi; surface type, maintenance level and open dates are the agency's own values for that segment, expanded from its codes and otherwise unedited. Nothing here says which road reaches the site.
EV chargers

Field check
On the agency's books. The land manager inventoried this site, so its existence is not in question — current conditions are. Nobody from here has camped it recently.
What we don’t know about Harkness Lake
A land record can put you within a few meters of a spot. It cannot tell you any of this — so check it yourself, and treat anything below as the open question it is.
- Road surface & last-mile access
- How many rigs actually fit
- Cell coverage by carrier
- Seasonal & winter access
- Current fire restrictions
- Whether any water here is drinkable
- Shade & wind exposure
- Noise and who else shows up
- Whether a listed EV charger works today, or the road miles to it
