Five ways The Mountain shows up

Every report (and every hex on the live map) lands on one of these five states. It's the whole language of Is The Mountain Out.

  1. 01

    Not out

    Socked in. The clouds win this round.

  2. 02

    Kinda out

    A peek: the summit teases through the haze.

  3. 03

    Halfway out

    Coming into view, the base still hidden.

  4. 04

    Mostly out

    Nearly the whole massif, clear and close.

  5. 05

    Mountain OUT!

    Full, unmistakable Tahoma. Go look.

Left to right: not out → Mountain OUT!

  • Fresh every reporting day, across the whole region.

Your data stays yours

Privacy-first by design

A community map shouldn't cost you your location. Here's exactly what we collect, and what we don't.

  • Approximate location only

    Your phone snaps your spot to an H3 resolution-10 hexagon, about a city block across (a few hundred feet), before anything is sent. We get the cell. We never get your raw GPS, and it stays on your device.

  • Report photos are scrubbed on upload

    Every photo you attach to a report is re-encoded on upload to strip all EXIF and GPS metadata, including the coordinates cameras quietly embed. Nothing about where you stood is hidden in the file.

  • Coarse map until it isn't noisy

    The public map shows reports at a wider hexagon size until enough people report from a smaller one. Locations stay at hexagon-grid resolution (roughly a city block), never your exact GPS.

  • Accounts are optional

    Reporting and reading the map never require an account. Anonymous reports are first-class. Sign up only if you want to attach photos, keep a streak, build a profile, or get notifications.

What we show the world

The map colors each hex cell by aggregated community consensus: how out The Mountain is, not your exact spot.

  • Not out
  • Kinda out
  • Halfway out
  • Mostly out
  • Mountain OUT!

About us

Built by mountain lovers
for mountain lovers.

Howdy. Is The Mountain Out is a side quest by Rainier Watch Supply Co., our apparel company out of the Pacific Northwest. Michael built the backend it runs on a couple of years back; these days it's mostly David on the site and the iOS app. It's the idea we'd had in our heads for years: a stupid-simple way to know, right this second, whether the Mountain is out. It's free and ad-free, and it always will be. Grabbing a shirt is how you keep it going.

The Mountain might be OUT right now.

Probably. Maybe. We don't know, that's exactly why we're asking you.
