They are (or were) called the Humboldt Abyss and Martel Sinkhole. They are located on the Sarisarinama Plateau at approximately 050000N0634600W. I looked at the foreign GNIS at http://164.214.2.59/gns/html/index.html but they are not listed. Also did an extensive web search with no luck. Any other ideas? If anybody knows about the area I am also interested in the best way to visit the site. This is a very remote site. The largest sinkhole is 1,200 ft in diameter and 1,000 ft deep, yet it's existence was reportedly unknown until 1954. It was first visited by scientists in 1974. In 1978 there were still no roads anywhere near this site. Mike Flannigan --- End Forwarded Message ---
