Granite: NH48 4000' Peaks

Every summit has a story. GRANITE unlocks all 48 New Hampshire 4000' peaks - their geology, history, and live weather - in one encyclopedia built for the mountains.

GRANITE is an encyclopedia of the 48 peaks on the New Hampshire four-thousand-foot list - the mountains that define the White Mountain landscape and have drawn hikers, climbers, and naturalists for more than two centuries.

Each entry goes beyond the trailhead. GRANITE covers the geology that shaped each summit, the history embedded in its name, the ecology of its alpine and subalpine zones, and the live weather forecast pulled directly from the National Weather Service. This is a reference app built for people who want to understand the mountains they are standing on - or planning to stand on.

Mount Washington is available free. All 48 peaks are unlocked with a single one-time purchase of $3.99. No subscription. No recurring charges. Buy it once and it's yours.

WHAT'S INSIDE EACH ENTRY

• Summit elevation, prominence, and coordinates from USGS 3DEP LiDAR data
• Geological profile - bedrock type, glacial history, how the summit took its shape
• Name history - the origin of every peak name
• Ecological notes on treeline, krummholz, and alpine plant communities
• Live summit forecast updated hourly via the NWS gridded forecast API
• Higher Summits Forecast for Presidential Range peaks, issued by Mount Washington Observatory meteorologists twice daily
• Selected trail access and route overviews

SUMMIT SEALS

Mark a peak as climbed and earn a summit seal - bronze, silver, or gold - recorded privately on your device. The first sixteen summits result in a bronze seal, the next sixteen makes them silver, and once you start on the final sixteen they all turn gold. The order doesn't matter. Your records never leave your phone.

THE PRESIDENTIAL RANGE

All nine Presidential peaks are included - Washington, Adams, Jefferson, Madison, Monroe, Eisenhower, Pierce, Jackson, and Clay - with full entries for each. The Observatory's Higher Summits Forecast appears on every Presidential entry, giving you the same professional forecast that guides decisions on the most exposed ridge in the northeastern United States.

THE SANDWICH RANGE, CARTER-MORIAH RANGE, AND BEYOND

GRANITE covers all 48 peaks across every range in the White Mountains - from the remote summits of the Pemigewasset Wilderness to the Sandwich Range peaks that rise above the Swift River Valley. Peaks with limited trail access and infrequently climbed summits receive the same depth of coverage as the well-traveled Presidential giants.

BUILT FOR THE MOUNTAINS

GRANITE was designed and written for people who take these peaks seriously. The entries are substantive. The data sources are primary. The weather is live. There are no ads, no tracking, and no data collected from your device.

One purchase. All 48. No subscription.
