Ecuador Ultra-Prominences

ECUADOR

15 Mountain Summits with Prominence of 1,500 meters or greater

Please send comments to webmaster.

This is one of eight lists that cover the known ultra-prominences for South America. This project represents original research into accurate elevations and prominence of the world's major summits, employing both new data sources and published topographic materials.

FOOTNOTES

Elevations of summits and saddles were all checked on 1:50,000 Instituto Geografico Nacional topographic maps. There seems to be a systematic bias in the elevations on the printed maps when compared to SRTM data, and in many cases we have overridden these elevations. Saddle elevations concur strongly, and most of these elevations will be within or close to the contour interval on the topographic map.

A further suggested resource is John Biggar's climbing guide "The Andes" and website.

[1] Chimborazo: Elevation of 6267m is based on a 1993 GPS survey by Mike Jenkins. Frequently given elevations of 6310m and 6272m should be considered older and obsolete. The 6267m value is said to be the new "official" elevation. SRTM analysis concurs that the true elevation is close to 6270m. Ecuadorian topographic maps are silent on the subject. Chimborazo was once considered to be the highest mountain in the world.

[4] We regard Cerro Altar (#4) as higher than nearby Volcan Sangay (#10). Our estimates of their respective elevations are based on SRTM data. The topographic maps state that Volcan Sangay is higher, in which case their respective prominences would be approximately reversed.

[5] Highpoint of the range is estimated from SRTM. Ecuadorian topographic maps are not available for the region. The TPC charts give a high elevation of 2999m.

[6] Cotacachi: 1:50,000 map gives 4939m, Biggar gives 4944m. SRTM is compatible.

[8] Antisana: The topographic maps give an elevation of 5,758 meters. This is incompatible with the SRTM data. We have estimated an elevation of 5704m.

[E1] Volcan La Cumbre, the highpoint of Isla Fernandina does not appear to be an ultra. Most internet sites repeat an elevation of 1463m. The Times Atlas gives a value of 1547m. We have elected to go with yet another published value of 1494m, which is the most consistent with our SRTM analysis.
