m spread (p95−p5, ~20–40 km window)

The county center sits at about 1,850 m above sea level. Elevation across the sampled window spreads 748 m — mountainous terrain by our banding (flat <30 m · gently rolling 30–100 m · hilly 100–300 m · mountainous >300 m). These are county-scale context, not parcel measurements — a specific parcel gets its own slope, flood and usable-acreage readings when analyzed.

Elevation measured 2026-07-21 from the AWS Terrain Tiles (terrarium encoding, z10).

Data available for Lewis and Clark County

  • Owner of record, parcel number, assessed value and the county's parcel boundaryMontana publishes these as open data (Montana State Library — MSDI Framework Parcels). LandBenchmark reads them directly.
  • Legal description — township, range and section from the BLM Public Land Survey System.
  • FEMA flood zones, wetlands, soil survey and NCCPI soil productivity — the federal layers, all free and all available here.
  • 56 measured signals from satellite imagery and public records — slope and usable acreage, observed surface water, vegetation trend, wildfire and seismic hazard, access and neighboring land use. Each one cites its method, its source, and the date it was observed.

LandBenchmark has no listings and does not know what is for sale in Lewis and Clark County. It analyses a parcel you point it at. It is an automated Phase-1 desk screen, not a survey, a flood determination, or a substitute for on-site inspection.

Common questions about land in Lewis and Clark County

Can I see who owns a parcel in Lewis and Clark County?

Yes — Montana publishes parcel ownership as open data (Montana State Library — MSDI Framework Parcels), so a LandBenchmark report on a Lewis and Clark County parcel shows the owner of record, parcel number and assessed value, cited to the state dataset.

How hilly is Lewis and Clark County?

Around the county center, measured elevation spreads 748 m across a ~20–40 km window — mountainous terrain by our banding. Individual parcels vary: a report measures the actual slope and usable acreage of the parcel you point it at.

What can LandBenchmark measure for a parcel in Lewis and Clark County?

56 measured signals, each cited with source and observation date: FEMA flood zone plus surface water observed in multi-year imagery, USFWS wetlands, USDA soil survey and productivity, slope and usable acreage, wildfire and seismic hazard, access and surroundings. What a satellite cannot verify — title, zoning, perc results, water rights — goes on a human-verify checklist naming the Lewis and Clark County offices that can.
