NH48.info is a volunteer‑run White Mountains reference centered on New Hampshire’s 48 four‑thousand‑foot peaks. The site now combines detailed peak guide pages, route and trail context, range-level browsing, photo-rich summit coverage, and a growing visual wiki for hikers, planners, researchers, and curious mountain people.
Most of the site is meant to be read like a normal guide first. You can open a peak page for elevation, prominence, routes, nearby links, photos, and map context, then branch into the trail explorer, range catalog, or wiki when you want a wider view. For builders and data users, authenticated API access is available for NH48 and NH52WAV when you need cloud fetches and managed keys.
