Editing Transverse Ranges (section)

===Climate===
The climate in most of the range is ''Csb'' ([[Mediterranean climate#Warm-summer Mediterranean climate|Warm-summer]] [[Mediterranean climate|Mediterranean]]) under the [[Köppen climate classification]]; the upper reaches of San Gorgonio Mountain have an alpine tundra climate (''ET''), while the lower northern slopes of the range have a desert (''BW'') or steppe (''BS'') climate; most of the nearby lowlands to the south and west have a Hot-summer Mediterranean climate (''Csa'').<ref>{{Cite web |url=http://www.spatial.redlands.edu/salton/WebAtlas/BiologyNM.swf |title=Redlands Biology |access-date=2014-10-21 |archive-date=2017-05-25 |archive-url=https://web.archive.org/web/20170525054535/http://www.spatial.redlands.edu/salton/WebAtlas/BiologyNM.swf |url-status=dead }}</ref>

Snow falls above {{convert|6000|ft}} most winters, and above {{convert|3000|ft|-2}} every few years. It is rare for elevations above {{convert|8000|ft|-3}} to go multiple winters without snow, even during severe droughts. Due to relatively low humidity, the regional [[snow line]] lies at about {{convert|14000-16000|ft|-3}}, above the highest elevation of the range; as such, snow does not persist year-round except in the form of [[snow patch]]es.

The tree line lies at about {{convert|11000|ft|-3}}; San Gorgonio Mountain is the only peak with an alpine environment.
