A field guide built from the record.
This independent Terrain360 project brings maps, published 360-degree trails, geological sites, erratics, and historical field notes into one searchable view of the Ice Age Floods landscape.
A terrain-first research and exploration tool.
Sites, erratics, field notes, research, flood reconstructions, and Terrain360 routes are presented together instead of living in separate collections.
The 360 catalog links 77 routes and 34,561 scenes throughout the flood corridor, including five routes assembled specifically for the Ice Age Floods collection.
Each generated page keeps its coordinates, survey details, descriptions, and available source links visible. Interpretation does not replace provenance.
Normalized, checked, and reproducible.
The catalog is generated from versioned GeoJSON. Automated checks flag missing names, invalid geometry, duplicate identifiers, shared coordinates, and state-classification errors before publishing.
Records are classified with U.S. Census TIGERweb state boundaries rather than rough coordinate boxes.
IAFI, NPS, USGS, state surveys, individual researchers, and Terrain360 are credited as sources where their material appears. Credit does not imply sponsorship or endorsement.
Ambiguous names, locations, and interpretation should be checked against the cited source. Terrain360 maintains the site and its technical presentation.
