Peak Catalog
NH48 Catalog
Browse New Hampshire’s forty eight four thousand footers as living mountain pages, not a bare checklist. Range by range, the catalog surfaces elevation, prominence, trail style, difficulty, exposure, and summit photography, then opens into full guides with route maps, weather context, parking notes, and field tested observations. Start here when you want the whole list to feel navigable rather than overwhelming.
- Live peak cards and range filters pull from the current NH48 catalog data.
- Cards surface elevation, prominence, trail type, and difficulty before you open the full mountain guide.
- Range browsing carries straight into guide pages with route maps, weather context, parking notes, and summit photography.
Search, range filters, and real NH48 cards will hydrate here as this panel approaches the viewport.
Current Conditions
Current Conditions
Check the lightweight live version of the NH48 Current Conditions page with a mini map, default temperature and alerts, summit hover details, and quick links into the full planning surface.
- Temperature and alert highlighting load first so the homepage preview stays useful without opening the full overlay stack.
- Hover, focus, or tap a summit marker to update the detail card and pin the peak you want to review.
- Primary and secondary actions jump straight into the full current-conditions page or the fullscreen NH48 map.
This panel hydrates with a compact live map, summit detail card, and default temperature plus alert context as it approaches the viewport.
NH48-First Trail Explorer
Multi-Region Trails
This is route browsing with the clutter removed. Pick a hiking area, then keep map, list, search, mileage, trail source, manager, and route shape filters in one shared view so you can compare options without losing your bearings. It feels less like opening another tool and more like standing over one clear map until the right trail reveals itself.
- The map, trail list, and filters stay in sync, with stable links into the full explorer.
- NH48 remains the default opening region, while the preview can still switch into any manifest backed trail dataset.
This panel hydrates with the live region list, featured trail picks, and a compact route map as you scroll into it.
Guide Layer
NH48 Guide
The guide is where the list becomes legible. It gathers the meaning of the NH48, range by range structure, classic day trip groupings, beginner picks, difficulty bands, seasonal and risk context, finish strategies, history, and the site’s data doorway into one readable planning spine. Read this before you sort peaks; it will change how you understand the whole project.
- Guide tables and grouping cards draw from the same datasets that feed the planner and live peak pages.
- The preview separates understanding the list from arranging trips, so visitors can learn the mountain families before launching the planner.
- Range filters, table rows, and grouping cards mirror the live guide structure rather than a thin homepage summary.
Range filters and compact guide rows will appear here from the live guide and planner grouping data.
Long-Distance Routes
Long Trails
The long trails system brings together the Appalachian Trail, Pacific Crest Trail, Continental Divide Trail, Arizona Trail, and other long campaigns with stable URLs, downloadable geometry, and section level metadata so immense routes become browsable one piece at a time. It invites big trail thinking without sacrificing structure.
- Section cards, mini maps, and exports all point back to the same route dataset.
- Preview routes surface section links, geography, and route identity before you open the full explorer.
Compact route cards and a mini long-trails map hydrate here from the generated section datasets.
Howker Flora
Howker Plant Catalog
This catalog follows Howker Ridge from alpine bilberry to bog plants, shrubs, mosses, and year round lichens, organized by habitat, season, and growth form with photo backed observations and field notes. Open it when you want the ridge to read not just as a route, but as a living ecological gradient.
- Habitat, season, and type filters turn the trail into a browsable field notebook.
- Species cards come from the live Howker plant catalog, with real images, notes, and habitat cues.
A live subset of the Howker plant catalog hydrates here with real species cards and type filters.
Trail Narrative
Howker Ridge Trail Info
Howker Ridge is presented here as a real mountain narrative rather than a generic hard hike blurb. The page tracks the climb from Bumpus Brook cascades and Devil’s Kitchen to the four scrambling Howks, ecological shifts, viewpoints, history, bailout options, loop variations, and the high alpine finish on Mount Madison beside the Appalachian Trail. Open this when you want terrain, story, and decision making in the same place.
- Live points of interest, route metrics, and map links keep the page anchored to the trail itself.
- Points of interest, highlights, and route context come from the same trail data files used on the destination pages.
- The panel still previews the narrative guide and the interactive map without trying to embed the whole project at once.
Route metrics, point-of-interest buttons, and a mini map preview load here from the live Howker Ridge data files.
Trip Building
NH48 Planning & Info
Planning here means more than sorting peaks by name. This hub pairs first hike guidance, day trip groupings, logistics and risk notes, and finish styles with a drag and group planner that lets you reorder all forty eight peaks into realistic trips before you export the sequence. It is equal parts strategy board, field notebook, and long game companion.
- Build trip blocks, collapse groups, and shape a finish strategy before the calendar fills in around you.
- The preview stays lightweight on the homepage while reflecting the same planning templates and grouped day trip families used in the full planner.
- Guide notes and planner actions stay aligned so visitors can move from strategy to itinerary without losing context.
Strategy filters and draggable itinerary groups hydrate here from the NH48 planner template data.
Photo Learning
Photo Games
The site’s photo archive becomes a training ground here. Match summit images to the right peak across the eight round PeakID game, race falling photos against the clock in timed mode, or rebuild a mountain as a jigsaw from real NH48 imagery. Playful on the surface, these modes quietly teach visual fluency with the mountains themselves.
- Three ways to learn the peaks: memory, speed, and pattern recognition.
- Each mode uses real summit photography from the NH48 archive rather than generic game art.
- The homepage preview lets visitors sample the game family before opening the full PeakID, timed, or puzzle experience.
A compact playable preview of each photo game mode will hydrate here using real mountain photos.
Companion List
NH52WAV
The companion list widens the horizon beyond the four thousand footers without lowering the level of detail. Searchable, range grouped cards lead into live NH52WAV peak guides with route context, trail maps, weather baselines, planning notes, and summit photography, making these scenic peaks feel like a true second landscape to explore rather than an afterthought.
- A broader New Hampshire mountain catalog, built with the same guide logic as the flagship NH48 pages.
- The homepage preview uses the real NH52WAV catalog renderer, search flow, and range slices.
- Direct peak links carry visitors from the companion list into full guide pages with maps, planning notes, and mountain imagery.
Searchable NH52WAV cards hydrate here using the same renderer and mountain data as the full catalog.
Field Guide Network
White Mountains Visual Wiki
This is the site’s knowledge web rather than its checklist. The visual wiki links NH48 mountains, NH52WAV peaks, plants, animals, and forest health threats into a browsable field encyclopedia, so a hike can unfold sideways, from summit to species, from forest type to disease pressure, from scenery to system. It is the best doorway for turning trail fascination into mountain literacy.
- Browse a mountain, then follow the links outward into flora, fauna, and the changing condition of the forest.
- The panel exposes live category counts and entry links from the same wiki datasets used on the destination pages.
- Visitors can move between mountains, plants, animals, and forest health while keeping the broader field guide context in view.
Live entry counts, category toggles, and connected wiki links hydrate here from the current mountain, plant, animal, and forest-health datasets.
NH48 is a guide-first hub for New Hampshire 4,000-footers and the wider White Mountains, with peak pages, trail tools, range catalogs, photos, and authenticated API access for cloud fetches.
