About this project

For IAFI, the chapters, and partners.

iceagefloodstrail.org is the public, interpretive home of the Ice Age Floods National Geologic Trail. This page gathers the project behind it: what it is, what it captures, how it is built, and who it is built with. For the public story, start at the main site.

Where this fits

A complement to IAFI, not a replacement.

The Ice Age Floods Institute has spent decades assembling the scholarship of the floods. This site is the immersive public front door for that work, surfaced to a national audience for the first time, with the 360° and photogrammetry layer IAFI’s existing platforms can’t host.

What this is

The official immersive public trail experience for the Ice Age Floods National Geologic Trail.

Storytelling, trip planning, deep site profiles, and an interactive map, built on top of IAFI’s data, fully attributed, with the immersive 360° / drone / photogrammetry capture layer added on by Terrain360.

What this isn’t

Not a replacement for iceagefloods.org or iafi.org.

IAFI carries on as the scholarly authority, the membership organization, and the chapter network. This site funnels public traffic to IAFI, new members, new donors, new field-trip attendees, not away from it.

Modeled on lewisandclarkresearch.org, the public research site for the Lewis & Clark Trust. Same architecture: scholarly organization keeps its identity; Terrain360 operates the immersive presentation layer. Zero operational burden on IAFI.
Phase 1 deliverables

What we capture, and how your chapters can use it.

Phase 1 spans four capture types, delivered in open formats that work in ArcGIS Online, Esri StoryMaps, Google Earth, Mapbox, and any modern web platform. The assets are yours, not locked to Terrain360.

Immersive corridors

360° panoramic capture

Walkable trails and shoreline corridors captured scene-by-scene at GPS-accurate locations. Hotspot overlays link to interpretive content. Used for hikes, drive routes, paddle corridors, and overlook sequences.

Delivery: equirectangular JPG sequences · Terrain360 trail viewers · embeddable iframes
Aerial perspective

Drone footage & aerial stills

For sites that can’t be walked or boated, Burlingame Canyon, Pantops, Williams Lake Cataract, Benton City Scablands, The Narrows, drone delivers the only practical way to capture the geometry of catastrophe from above.

Delivery: 4K MP4 sequences · geo-tagged stills · orthomosaic where feasible
Walkable 3D models

Photogrammetry & Gaussian splat models

Erratics, small point-locations, and signature geologic features captured as fully-walkable 3D models. Dry Falls overlook, Steamboat Rock, Ginkgo Petrified Forest, Steptoe, Spokane Falls, and named erratics including the Bretz-identified boulders.

Delivery: glTF / GLB · USDZ for iOS AR · Gaussian splat (.ply / .splat) · web viewer with measurement tools
Portable, not locked in

Multi-format, partner-ready

Every asset is exported in the open formats your chapters and state agencies already use. Drop them into the platforms your audiences already live in, we hand over working files, not a black box.

Compatible with: ArcGIS Online · Esri StoryMaps · Google Earth (KMZ) · Mapbox (GeoJSON) · modern web (glTF / USDZ)
The full vision

Eight sections. One coherent home for the trail.

This is what iceagefloodstrail.org becomes alongside the Phase 1 field capture, the official public-facing trail experience that integrates IAFI’s scholarship and Terrain360’s immersive capture.

01

Home

Hero map, latest captures, what is the Ice Age Floods Trail.

In Phase 1
02

The Trail Map

The full interactive Terrain360 map, cinematic intro, 3D flood timeline, split view, every captured site.

In Phase 1
03

Sites

Deep page per geologic location. 360° capture, drone, photogrammetry, geologic context, Bretz commentary.

~10 hero sites in Phase 1, full 138 in Phase 2
04

The Floods Story

Narrative timeline from ice dam breach to today. Embedded 3D visualization. Scale comparisons.

In Phase 1
05

Research

Bretz, Pardee, O’Connor, Bjornstad archive. IAFI scholarship surfaced to the public. Scholar bios.

Scaffolded in Phase 1
06

Chapters & Regions

One page per IAFI chapter and per geologic region. Each chapter gets a public home.

Scaffolded in Phase 1
07

Plan a Visit

Itineraries, drive routes, seasonal notes, accessibility, partner integrations with state tourism.

Scaffolded in Phase 1
08

About & Get Involved

IAFI front and center. Membership funnel, donation, partner attribution, dream-team bios.

In Phase 1
Phased delivery

Phase 1 is the start, not the finish.

The Phase 1 capture campaign already in your hands funds the build. Phases 2 and 3 are the roadmap that makes the trail a national destination.
