This blog covers the questions that come up on trails, at viewpoints, and from airplane windows: how to tell one summit from another, what elevation and prominence actually mean, which famous peaks you can see from where, and how the great mountains earned their reputations. Plain English, real figures, no guidebook padding — and where a figure is genuinely contested or re-surveyed, we say so instead of rounding the uncertainty away. Start with the identification guide if you're new to peak-spotting, or jump straight into a famous summit like the Matterhorn or Denali.
How these articles are written
Every figure — heights, prominences, first ascents — traces to a named source listed at the end of each article, and where the sources themselves hedge (survey years, shifting snow caps), we keep the hedge rather than inventing precision. Articles carry the The Mountain Identifier Team byline, are fact-checked before they publish, and get corrected rather than left stale when the numbers move. Spot an error? Tell us — the correction wins.
