This cover contains the outlines of recent landslides formed prior to Hurricane Mitch in October - November 1998. Jeffrey Coe and Robert Bucknam mapped the landslides. Most landslides were mapped using 1:40,000-scale aerial photographs and a Kern PG-2 photogrammetric plotter at 4X and 8X magnifications. The photographs were scaled and oriented to the topographic base map using prominent topographic landmarks and plotted on a transparent polyester overlay registered to the topographic base maps at scales of 1:50,000 or 1:25,000. In areas where landslides were very sparse, the aerial photographs were scanned with a mirror stereoscope at 4X magnification, and landslide locations were transferred to base maps by inspection....

The Digital Chart of the World (DCW) is an Environmental Systems Research Institute, Inc. (ESRI) product originally developed for the US Defense Mapping Agency (DMA) using DMA data. The DCW 1993 version at 1:1,000,000 scale was used. The DMA data sources are aeronautical charts, which emphasize landmarks important from flying altitudes. This explains why there is a separate aeronautical theme with all conceivable airports, yet why on some themes small islands and lakes are simply unnamed points. ESRI, in compiling the DCW, also eliminated some detail and made some assumptions for handling tiny polygons and edgematching. Also, note that the completeness of the thematic categories present in each layer will vary....

Album caption: Stela F. One of the most distinctive of the stela at Quirigua. It projects 24 feet above the ground. This is the south face and the glyphs are perhaps the most beautifully carved of any among the Maya inscriptions. An unusual feature of this stela is that it has two dates - A.D. 1761 and A.D. 724 which is likely a leap year correction. While Stela F. is one of the tallest here it is not the tallest. Stela E. is the tallest. It is 35 feet long by 5 feet wide and 4 feet thick. It projects 26 feet 6 inches above ground and weights 65 tons. It is the largest piece of stone every quarried by the Maya. Guatemala. 1922. No index card. The Ruins of Quirigua, Guatemala - This Maya archeological site is...

This cover contains the outlines of landslides formed during Hurricane Mitch in October - November 1998. Jeffrey Coe and Robert Bucknam mapped the landslides and related effects in and adjacent to downstream drainages.
