The Bolivian Amazon
September 13, 2002 - An 8-kilometer (5-mile) wide crater of possible impact origin is shown in this view of an isolated part of the Bolivian Amazon from the Shuttle Radar Topography Mission. The circular feature at the center-left of the image, known as the Iturralde Structure, is possibly the Earths most recent big impact event recording collision with a meteor or comet that might have occurred between 11, 000 and 30, 000 years ago.
Lying in an area of very low relief, the landform is a quasi-circular closed depression only about 20 meters (66 feet) in depth, with sharply defined sub-angular rim materials. It resembles a cookie cutter in that its appearance cuts the heavily vegetated soft-sediments and pampas of this part of Bolivia.
Two visualization methods were combined to produce this image: shading and color coding of topographic height. The shade image was derived by computing topographic slope in the northwest-southeast direction. North-facing slopes appear bright and south-facing slopes appear dark. Color coding is directly related to topographic height, with brown and green at the lower elevations, rising through yellow and brown to white at the highest elevations

EDITORS COMMENTS
This print captures the breathtaking beauty of the Bolivian Amazon, revealing a hidden secret within its lush greenery. Taken on September 13,2002, during the Shuttle Radar Topography Mission, it showcases an extraordinary sight - an enormous crater with a possible impact origin. Known as the Iturralde Structure, this circular feature at the center-left of the image is believed to be one of Earth's most recent significant collision events with a meteor or comet. Located in an isolated part of Bolivia's Amazon rainforest, this landform stands out amidst its surroundings due to its unique characteristics. With a depth of only about 20 meters (66 feet), it forms a quasi-circular closed depression and boasts sharply defined sub-angular rim materials. Its appearance resembles that of a cookie cutter slicing through the heavily vegetated soft-sediments and pampas in this region. To create this stunning image, two visualization methods were combined: shading and color coding based on topographic height. The shade image highlights topographic slope by illuminating north-facing slopes brightly while casting south-facing slopes into darkness. Meanwhile, color coding represents different elevations - from brown and green at lower levels to yellow and brown rising towards white at higher elevations. This mesmerizing photograph by Stocktrek Images not only offers us a glimpse into our planet's geological history but also serves as a reminder of nature's awe-inspiring power and resilience.
