Why the World's Tallest Waterfall Is Named Angel Falls
terrae incognitae, Vol. 44 No. 1, April, 2012, 16–42 Why the World’s Tallest Waterfall is Named Angel Falls Karen Angel Eureka, California, USA Jimmie Angel (1899–1956) was an aviator and adventurer in the early years of air exploration. This article discusses his discovery of Angel Falls, the world’s tallest waterfall, which bears his name, and the impact of that discovery — and his reputation and dogged determination — on later expeditions into the Venezuelan interior. The author, Angel’s niece, pieces together this fascinating story using a blend of dedicated archival research and painstakingly acquired family history and the reminiscences of friends and acquaintances of Jimmie and his wife Marie. The result is a tale of modern-day exploration and geographic discovery. keywords Jimmie Angel, Angel Falls, Auyántepui, E. Thomas Gilliard, Anne Roe Simpson, George Gaylord Simpson, Venezuela When I began researching the life of American aviator James “Jimmie” Crawford Angel (1899–1956), there were many stories about him in books, newspapers, magazines, and more recently on websites and blogs. Some stories can be verified by the Angel family or other sources; some stories are plausible, but remain unverified; other stories are fabrications. The result is a tangle of true stories and unverified stories. Finding the truth about Jimmie Angel is also complicated because he himself repeated the various unverified stories that became legends about his life.1 As the daughter of Jimmie Angel’s youngest brother Clyde Marshall Angel (1917– 97), I had heard stories about my uncle since childhood, but the family had few documents to support the stories. -

This species inhabits rainforest on granitic substrate on the northwestern edge of the Guiana Shield (Estado Amazonas, Venezuela). The new species is distinguished from congeners by sexual dimorphism, its unique male color pattern (including two bright orange parotoid marks and two orange paracloacal spots on dark brown background), call characteristics and other morphological features. Though to the new species is known only from the northwestern edge of the Guiana Shield, its distribution may be more extensive, as there are no significant biogeographic barriers isolating the type locality from the granitic lowlands of Venezuela.

Abstract: Venezuelan Table Mountains (tepuis) are among world’s most unique ecological systems and have been shown to have high incidence of endemics. The top of Roraima, the highest Venezuelan tepui, represents an isolated enclave of species without any contact with the surrounding landscape. Daily precipitation enables algae and cyanobacteria to cover the otherwise bare substrate surfaces on the summit in form of a black biofilm. In the present study, 139 samples collected over 4 years from various biotopes (vertical and horizontal moist rock walls, small rock pools, peat bogs, and small streams and waterfalls) were collected and examined for algal diversity and species composition. A very diverse algal flora was recognized in the habitats of the top of Mt. Roraima; 96 Bacillariophyceae, 44 Cyanobacteria including two species new to science, 37 Desmidiales, 5 Zygnematales, 6 Chlorophyta, 1 Klebsormidiales, 1 Rhodophyta, 1 Dinophyta, and 1 Euglenophyta were identified. Crucial part of the total biomass consisted of Cyanobacteria; other significantly represented groups were Zygnematales and Desmidiales. -
Shrouds of Mystery
Story Giles Foden Photographs Philip Lee Harvey SHROUDS OF MYSTERY Venezuela’s bizarre antediluvian landscape hides many secrets, tempting fearless adventurers over the years with the possibility of riches and even enlightenment The waterfall seemed to fall through eternity. Sifted in the sieve of itself – hovering in the air, staggering but never stopping – it appeared to be part of a world in which time had slowed down, or somehow been canceled altogether. There are verifiable reasons to explain how this impression could form in my head. Water from above was decelerating as it hit water below, water that had itself already slowed down – and so on and on. The phenomenon that is Angel Falls comes down in some of the world’s oldest natural formations: the table- like “tepui” mountains that rise, suddenly and inconceivably, from the Gran Sabana. This vast area of grassland and jungle is the heartland of Venezuela. The tepuis themselves are remnant geological features of Gondwanaland, Myth and legend surround a supercontinent that existed some 180 million years ago, when Africa and South America were conjoined. It was the American pilot Jimmie no wonder I felt out of time. Angel, after whom Angel Falls in Venezuela is Silent and amazed, perched on a rocky outcrop opposite the falls, I watched the cascade’s foaming sections, named. He was born streaming and checking in the roaring flow. At 3,212 feet high, Angel Falls is the world’s tallest waterfall, a “vertical in Missouri in 1899 river” that has mesmerized many before me. With a flash of insight, I realized its movement exemplified humanity’s never-ending Auyántepui, the mountain from which it descends, reads like dance between holism and separation; everything is connected, something out of a novel. -

Eastern Tepuis Adventure Venezuela
Eastern Tepuis Adventure Venezuela The Tepuis (Tepuys) of Venezuela are among the most spectacular mountains on Earth. They are mysterious and gigantic sandstone plateaus that are encircled on all sides by vertical cliffs that soar hundreds of metres high. The summits of many of the Tepuis have been isolated for millions of years and remain little explored. They are home to unearthly landscapes of sculpted rock, and a plethora of unique plant and animal wildlife. This expedition offers the rare opportunity to photograph a wide range of spectacular landscapes and wildlife. The Eastern Tepuis are stoney and dramatic, but exceptionally beautiful. A diverse range of amphibians, reptiles, birds and insects call the Eastern Tepuis home, as well as hundreds of species of orchids and ferns, and many carnivorous plants, including Brocchinia, Drosera, Genlisea, Heliamphora and Utricularia. Most of the Eastern Tepuis are accessible only by helicopter. This expedition will comprise a group of twelve people; two expedition leaders and ten participants. We will undertake four helicopter flights (each flight transporting 4 people) to transfer the group to each location on the itinerary. Due to the helicopter’s passenger limits and the complicated logistics of this trip, ONLY TEN PLACES are available for this expedition. COST: £3,500 per person for 15 days / 14 nights (all inclusive from start point to end point). START POINT: Boa Vista, Brazil. END POINT: Boa Vista, Brazil. DATES: To be agreed as a group - please email to discuss and to find a mutually convenient time. GROUP SIZE: 10 BESPOKE TOUR: Alternatively, if you do not wish to join a group tour, we can customise a private trip to fit your dates and suit your interests. -
Venezuela Tepuis
TRIPLIST Venezuela Tepuis February 2, 2007 to February 11, 2007 Guided by Jay VanderGaast For the past two years our tepuis trips have been characterized by fairly wet weather and relatively cool temperatures along the Escalera Road. So I was surprised by how very hot and dry conditions were this year. There had been no rain in the region for a couple of weeks, and where there had been deep mud and several inches of standing water on past trips, this year there was virtually none. And where clouds had obscured much of the scenery on the Gran Sabana in the past, this year's clear weather allowed us unobstructed views across the savanna, with tepui views unlike I had ever seen before! While this lack of damp weather did have a dampening effect on the bird activity, it certainly didn't dampen our enthusiasm for birding in this wonderful corner of the country. Though quieter than usual, there were, of course, still plenty of birds to be seen, and plenty of memorable encounters with the pan-tepui endemics. Several days of working the upper reaches of the Escalera Road rewarded us with about 27 of the region's specialties, and some of the normally difficult to find species gave themselves up without much of a fight this year: a Greater Flowerpiercer living up to its name in a roadside flower bank; a very confiding pair of Roraiman Barbtails working methodically through the lower levels of stunted melastome forest, a pair of gorgeous Red-banded Furiteaters feeding quietly in a nearby fruiting tree. -

The Truth About Jimmie Angel & Angel Falls
Alexander von Humboldt Conference 2005 Centro Universitario Hispano Mexicano Veracruz, Mexico Why the World’s Highest Waterfall is Named Angel Falls The Phelps Venezuela Expedition Years of Exploration 1937-1938 by Karen Angel Why is the world’s highest waterfall named Angel Falls? It could be because the name is descriptive of the wing of water that falls from the heavenly clouds hovering over Auyan-tepui, its mountain home. In fact, it is named for Jimmie Angel, an earthy North American aviator-explorer born in 1899 in the state of Missouri1 Why the waterfall came to be named Angel Falls in honor of Jimmie Angel, I believe, is largely due to the vivid writings of E. Thomas Gilliard, a young scientist from the American Museum of Natural History who explored Auyan-tepui in 1937-1938 as a member of the Phelps Venezuela Expedition.2 According to legend, Jimmie Angel’s first trip to Venezuela was in the 1920s with an American mining geologist from Colorado known as McCracken. The two met in a bar in Panama and agreed that McCracken would pay Angel $5,000 to fly him to a secret location. At McCracken’s direction, Angel landed his airplane on a mysterious tepui in the Gran Sabana region of Southeastern Venezuela. Together, they removed many pounds of gold from a river on top of the tepui. After McCracken died in the United States a few years later, Angel spent the balance of his life looking for the river of gold. In his search, Angel became obsessed with Auyan-tepui; a 435 square mile heart shaped tepui not shown on the maps prior to his explorations of the region.3 He believed that it was the home of the lost river of gold.
