Pico Humboldt
Glaciers
The summit was formerly surrounded by glaciers, including the two largest out of the four glaciers remaining in the country (the other two smaller glaciers were on Pico Bolívar). The glaciers on Humboldt Peak (as most tropical glaciers) have been receding fast since the 1970s. By 2009, all but one glacier, the Humboldt Glacier, had vanished. In 2019, the remaining glacier covers an area of 0.1 km and was forecast to melt completely within a decade: in May 2024, the Humboldt Glacier was officially downgraded to an ice field, no longer considered a glacier.
Glacier ecosystem
Humboldt peak also hosts the last remnant of the Tropical glacier ecosystem of the Cordillera de Merida. This ecosystem is formed by the interconnected remaining ice substrate, proglacial lakes and glacier forefield. As the ice substrate declines, the risk of losing these connections increases and the ecosystem is considered critically endangered (category CR) with high risk of imminent collapse, according to a recent IUCN Red List of Ecosystems assessment.
