Mountain in Sololá, Guatemala
From Wikipedia, the free encyclopedia
Tolimán, also known as Volcán Tolimán, is a stratovolcano in Guatemala, on the southern shores of Lake Atitlán. Part of the Sierra Madre mountain range, the volcano has an elevation of 3,158 m (10,361 ft) and was formed near the southern margin of the Pleistocene Atitlán III caldera. The top of the volcano has a shallow crater and its flanks are covered with the thick remains of ancient lava flows that emerged from vents in the volcano's flanks.

Cerro de Oro
A parasitic lava dome, known as Cerro de Oro, was formed on the volcano's northern flank, which may have erupted a few thousand years ago.
The following table synthesizes the primary geomorphological features, parasitic structures, and ecological zones associated with Volcán Tolimán:
| Sector / Structure | Elevation Range | Geological Features & Volcanology | Ecosystem & Associated Biodiversity |
|---|---|---|---|
| Main Summit Crater | 3,158 m (10,361 ft) | Shallow, elliptical crater with thick late-Pleistocene and Holocene andesite and dacite flows | High-altitude cloud forest featuring oak-pine mix, mosses, and epiphytes. |
| Northern Flank Lava Flows | 1,800–2,600 m | Massive lava lobes extending down to the southern shore of Lake Atitlán | Dense tropical montane forest and shade-grown coffee agricultural plots. |
| Cerro de Oro Dome | 1,895 m (6,217 ft) | Parasitic lava dome formed on the lower northern flank near the lake shore | Habitat for endemic bird species, including the horned guan (Oreophasis derbianus). |
