Peakbagger.com
website about mountains in the United States and Canada
Peakbagger.com is an American free online public database of mountain summits, primarily geared towards highpointers and peakbaggers created by Greg Slayden in 1987 and launched in 2004.
Overview
Peakbagger.com offers its users the ability to log ascents, write trip reports, make lists of summits, upload GPX tracks, and add summits to its database. The Peakbagger.com database features over 200,000 individually documented summits worldwide and is a significant resource for trip reports and route directions, especially for obscure summits.
Notable users of Peakbagger.com include Eric Gilbertson.
Peakbagger.com has garnered criticism for promoting trespassing, as some specific peaks, especially certain county high points, are on private property. Despite this, Peakbagger explicitly states on its front page that it does not condone any dangerous or illegal activity, and peaks that are on private land are tagged as such.
History
Peakbagger.com was originally devised by American mountaineer and programmer Greg Slayden in 1987, initially being a simple text file listing mountains. In 1997, the Peakbagger.com domain was launched, with the mountain database being released in 2004. Peakbagger.com has had its functionality continually updated since, but had its last major visual update in 2004.
At some point in the 2010s, a free Peakbagger app was developed by Andrew Kirmse for IOS and Android devices.

Why this record matters

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 21, 2026. The linked authority identifier is Q28736250. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1987, 2004 and 1997.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
