Sample 360° capture

Eagle Creek to Hole in the Wall, Upper Missouri.

A live example of what the Minot Air Force Base corridor would look like after capture, drawn from existing Terrain360 work in the region.

EXAMPLE Eagle Creek to Hole in the Wall, Upper Missouri. Reference capture · Upper Missouri Breaks. EXAMPLE from existing Terrain360 capture in the Upper Missouri Breaks National Monument — the same Missouri River system the Minot corridor capture would document from Garrison Dam through the Fort Mandan / Knife River reaches.

Corridor narrative

Why this corridor.

Minot Air Force Base anchors the most historically dense stretch of the Lewis & Clark Trail outside the Great Falls portage. Fort Mandan — where the Corps wintered 1804-05 and where Sacagawea joined the expedition — sits ~55 miles south of the base. The Knife River Indian Villages National Historic Site, a Hidatsa and Mandan settlement complex where Sacagawea actually lived, lies ~70 miles south.

The corridor itself is a continuous ribbon of L&C-direct recreation assets: Lake Sakakawea (the impounded Missouri), Lake Audubon NWR, Cross Ranch State Park, Fort Stevenson State Park, and the North Country National Scenic Trail's Lake Sakakawea segment all sit inside the same Phase 2 footprint. Knife River Indian Villages NHS is NPS-managed; Fort Mandan is state-park-interpreted with a Lewis & Clark Interpretive Center.

Minot is a heavy-mission base — 5th Bomb Wing (B-52H) and 91st Missile Wing (Minuteman III) — and the only base in the program whose REPI footprint can directly seed recreation capture across the iconic Sacagawea / Mandan winter-quarters reach.

Lewis & Clark connection

~55 mi NW of Fort Mandan (L&C 1804-05 winter quarters near Washburn). The Knife River Indian Villages NHS — where Sacagawea joined the Corps — sits ~70 mi south. Dual-mission base: 5th Bomb Wing (B-52H) + 91st Missile Wing (Minuteman III).

Directly on the LCNHT Missouri River corridor. Fort Mandan (1804-05 winter quarters) lies ~55 miles south; Knife River Indian Villages NHS (where Sacagawea joined the expedition) sits ~70 miles south. Garrison Reach of the Missouri, Lake Sakakawea, and Lake Audubon NWR all sit inside the corridor footprint.

ND's L&C narrative is the strongest of any phase 2 candidate — Fort Mandan winter quarters, Knife River Sacagawea site, and the entire Lake Sakakawea / Garrison Reach are all within the corridor footprint.

Final deliverables

What the partnership receives.

Hosted 360° portal

Web-based interactive map showing pan-and-explore imagery of both riverbanks and every mapped trail. Mobile + desktop. Embeddable in any partner site.

Geo-referenced imagery dataset

Equirectangular panoramas + GPS tracks delivered to the installation INRMP team and the NPS Trail Office for reuse in REPI reporting, ESA Section 7, and outreach.

Printable corridor maps

Asset index keyed to the imagery - suitable for visitor information, grant deliverable documentation, and partner co-branding.

L&C interpretive layer (optional)

Waypoint overlay tying the corridor to journal entries and historic sites - Tower Rock, Gates of the Mountains, the Falls portage, the Pacific arrival.

Asset inventory

Every asset, costed.

Each row is a discrete 360-mapping unit. Rivers are priced per mile of both-bank boat capture; trails per mile; access sites as fixed 360 nodes.
