Sample 360° capture

Palouse Falls to Lyons Ferry, Snake River WA.

A live example of what the Yakima Training Center corridor would look like after capture, drawn from existing Terrain360 work in the region.

EXAMPLE Palouse Falls to Lyons Ferry, Snake River WA. ≈ 70 mi E of Yakima. EXAMPLE from existing Terrain360 capture of the Snake River between Palouse Falls and Lyons Ferry, just east of Yakima Training Center in the same Columbia/Snake drainage. The Yakima corridor capture would extend this both-bank methodology to the Hanford Reach, Yakima Canyon, and the Sacajawea State Park confluence. Open full tour ↗

Corridor narrative

Why this corridor.

Yakima Training Center sits between two LCNHT-anchor reaches: the free-flowing Hanford Reach of the Columbia and the Sacajawea State Park confluence where the Snake meets the Columbia, the Corps' October 1805 camp. The Yakima River Canyon (BLM) and the Tapteal Water Trail close the loop with another 57 miles of paddleable river.

The Palouse to Cascades State Park Trail physically crosses YTC for 23 miles under Army/State co-management, a natural existing partnership that would extend cleanly into a recreation-corridor capture. Cowiche Canyon and Rocky Top add hiking and MTB networks on the west side.

Although YTC is managed under JBLM rather than as its own Sentinel Landscape, the corridor's three rivers + a historic-trail crossing + a direct LCNHT confluence camp make it one of the program's strongest recreation-and-history packages.

Lewis & Clark connection

Near-corridor on the Yakima and free-flowing Hanford Reach of the Columbia; direct LCNHT anchor at Sacajawea State Park (Snake/Columbia confluence, 1805 camp).

Near-corridor on the Yakima River and the free-flowing Hanford Reach of the Columbia; direct LCNHT anchor at Sacajawea State Park at the Snake/Columbia confluence, where the Corps camped in October 1805.

Palouse to Cascades State Park Trail physically crosses YTC (~23 mi Army/State co-managed) — a natural partnership fit.

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.
