Lizard Head is a mountain summit in the San Miguel Mountains range of the Rocky Mountains of North America. The {{convert|13119|ft|0|adj=on}} is located in the Lizard Head Wilderness, {{convert|11.0|km|order=flip}} west by south (bearing 258°) of the town of Ophir, Colorado, United States, on the drainage divide separating San Juan National Forest and Dolores County from Uncompahgre National Forest and San Miguel County.

Mountain

Lizard Head lies just southeast of a group of three Colorado fourteeners (mountains over 14,00 feet high), Mount Wilson, Wilson Peak, and El Diente Peak. Lizard Head is only the 556th highest peak in Colorado by most standard definitions,

but its towering spire-like form makes it one of the most spectacular.

Lizard Head lies {{convert|2.84|mi|abbr=on}} northwest of Colorado State Highway 145 at Lizard Head Pass. Lizards Head Trail climbs west from Trout Lake along Black Face Mountain ridge and past the south face of Lizard Head toward Wilson Peak.Mount Wilson, Colorado, 7.5 Minute Topographic Quadrangle, USGS, 1953

The peak was used in a logo by the Rio Grande Southern Railroad.{{cn|date=December 2024}}

Geology

The rock spire of Lizard Head looks like an old eroded volcanic plug but it is actually composed of extrusive volcanic ash flows of Oligocene age resting on older sedimentary rocks of Eocene age.{{cite book|chapter-url=http://geosurvey.state.co.us/education/Documents/Geology_of_the_Western_San_Juan_Mountains_and_a_Tour_of_the_San_Juan_Skyway,Southwestern_Colorado.PDF|last=Blair|first=Ron|chapter=Geology of the Western San Juan Mountains and a Tour of the San Juan Skyway, Southwestern Colorado|editor-last=Blair|editor-first=Ron|year=1996|title=The Western San Juan Mountains: their geology, ecology and human history|archiveurl=https://web.archive.org/web/20131228031812/http://geosurvey.state.co.us/education/Documents/Geology_of_the_Western_San_Juan_Mountains_and_a_Tour_of_the_San_Juan_Skyway,Southwestern_Colorado.PDF |archivedate=2013-12-28|url-status=dead|publisher=University Press of Colorado|accessdate=2013-07-12}}

Climbing

Lizard Head is one of the most difficult summits in Colorado to climb.

Describing the first ascent, Albert Ellingwood said:

{{Blockquote|A rottener mass of rock is inconceivable. The core may still be solid but the "surrounding tuffs" are seeking a lower level in large quantities. This far-advanced disintegration was our greatest obstacle. Absolutely the whole surface of the rock is loose and pebbles rain down from the sides as readily as needles from an aging Christmas tree. In many places one could with one hand pull down hundreds of pounds of fragments, and occasionally we could hear the crashing of small avalanches that fell without human prompting.{{cite journal

The first ascent team completed the climb and descent safely.{{cn|date=December 2024}}

Appearance

The appearance of the peak is reported to have changed significantly due to a landslide in 1911. From the December 29 edition of the Mancos Times-Tribune of that year:

{{Blockquote|Lizard Head has fallen

The skyline of the mountains to the southwest of Telluride was changed last night when through some mighty upheaval of nature, the taller spire of Lizard Head fell with a roar to the depths below.

During the night people living on the mesas near Ophir heard a sliding, grinding noise, which disturbed the atmosphere and gave the impression of an earthquake. This morning they discovered that the upstanding rock which had been given the name of Lizard Head was gone.

The smaller spire which was formerly inconspicuous by the side of the head is now standing single and alone, pointing to the sky, a long sentinel of last night’s upheaval. Millions of tons of rocks, conglomerate and earth went down without apparent cause or reason.{{cite news|url=http://www.cortezjournal.com/article/20120601/COLUMNISTS25/706019949|newspaper=Mancos Times-Tribune|date=December 29, 1911|title=Lizard Head has fallen|via=The Cortez Journal: "Lizard Head has changed landscape of SW Colorado"|archive-url=https://web.archive.org/web/20141213023750/http://www.cortezjournal.com/article/20120601/COLUMNISTS25/706019949|archive-date=2014-12-13|url-status=dead}}}}

There are several photographs of the peak from before the landslide. Before-and-after photographs taken from the north and shown in The RGS Story {{cite book|last1=Collman|first1=Russ|first2=Dell A|last2=McCoy|first3=William A|last3=Graves|series=THE R.G.S. STORY: RIO GRANDE SOUTHERN|volume=4|title=Over the Bridges, Ophir Loop to Rico, Sundance Books|year=1994|isbn=0913582743}} indicate substantial change. The earlier photograph shows a taller squared-off peak that would be more suggestive of a lizard's head.

Before-and-after photos shown in Jackson and Fielder's Colorado 1870-2000 {{cite book|first1=WH|last1=Jackson|first2=John|last2=Fielder|title=Colorado 1870-2000|publisher=Westcliffe Publishers with the Colorado Historical Society|year=1999|isbn=1565793471}} taken from the south do not show as much change in appearance, indicating that the area of collapse was on the northern side.
