The Treasure Valley sits in a high desert bowl at the confluence of the Boise and Snake Rivers. Six weather stations spanning 505 meters of elevation — from Homedale at 679m on the Snake River to the Boise Foothills at 1,184m — record a climate story that no single station can tell alone. Every daily observation since 1916 is here, provenance-stamped to NOAA GHCND, machine-readable, and connected by typed graph edges to agriculture, construction, water rights, and outdoor recreation. This is not a weather widget. This is the causal substrate of the Treasure Valley — the climate record that explains why the region is structured the way it is legally, economically, and physically.
