Lakes of Grand Teton National Park
Open-knowledge reference entry
There are 44 named and countless unnamed lakes in Grand Teton National Park. The largest of these is Jackson Lake, a natural glacial lake that has been enlarged with the construction of the Jackson Lake Dam. The lakes range in size as well as ease of access. In addition to mountain tarns, there are several large peidmont lakes. Nearly all the lakes are glacial in origin, formed by glacial action that carved out the valleys and left moraine behind that acted as dams to lock in water.
The lakes exist in the near pristine wilderness environment of the park, and recreational use, boating and fishing varies by lake. Elevation of the region classes these as alpine lakes, with Jackson lake being the largest alpine lake in the United States.
Overview
At its formation in 1929, Grand Teton National Park encompassed just six main lakes at the foot of the park's major peaks, but with the expansion of the park there are now 44 named lakes within the boundary, and countless smaller unnamed lakes and ponds. The peaks were raised in relatively recent geological time and carved by glaciers in the ica age. Most of the lakes in the park were formed by glaciers, which carved out the valleys they sit in, and where glacial morraine formed the dams that created the lakes.
This brief starts where responsible research should: with the source description of “Lakes of Grand Teton National Park” as open-knowledge reference entry. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as open-knowledge reference entry. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 10, 2026. The linked authority identifier is Q114044398. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1929.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
