Geology of the Loess Hills, Iowa Many Americans think of Iowa as having little topographic variation. However, in westernmost Iowa the Loess Hills rise 200 feet above the flat plains forming a narrow band running north-south 200 miles along the Missouri River. The steep angles and sharp bluffs on the western side of the Loess Hills are in sharp contrast to the flat rectangular cropfields of the Missouri River flood plain. From the east, gently rolling hills blend into steep ridges. Loess (pronounced "luss"), is German for loose or crumbly. It is a gritty, lightweight, porous material composed of tightly packed grains of quartz, feldspar, mica, and other minerals. Loess is the source of most of our Nation's rich agricultural soils and is common in the U.S. and around the world. However, Iowa's Loess Hills are unusual because the layers of loess are extraordinarily thick, as much as 200 feet in some places. The extreme thickness of the loess layers and the intricately carved terrain of the Loess Hills make them a rare geologic feature. Shaanxi, China, is the only other location where loess layers are as deep and extensive. Though much older (2.5 million years) and much thicker (nearly 300 feet) than Iowa's loess, the Shaanxi loess hills have been greatly altered by both natural and human activity and no longer retain their original characteristics. Origin of the Loess Hills Although early geologists assumed loess was either fluvial (deposited by a river) or lacustrine (formed in a lake), today we know that loess was eolian (deposited by the wind). During the Ice Age, glaciers advanced down into the mid-continent of North America, grinding underlying rock into a fine powderlike sediment called "glacial flour." As temperatures warmed, the glaciers melted and enormous amounts of water and sediment rushed down the Missouri River valley. The sediment was eventually deposited on flood plains downstream, creating huge mud flats.

Contact Us Last updated Some Related Links Comments on Organization of this page: As you might have guessed by now, the links put up at this site connect sites with subjects of interest related to ART. In instances where sites are not listed under a specific subject, they relate to GIS and related topics. This page is organized partly by TYPE OF ORGANIZATION (government/private/commercial) and partly by SUBJECT (remote sensing/geography). Our attempt has been to use both paradigms to index sites that will fall sometimes in both- like the NASA - Remote Sensing Data and Information site into just one topic that will best list for our purposes. A lot of the sites listed below are not just about the title they are listed under; the title describes best to our understanding, a major part of their work or purpose as gleaned from their material and mission statement. So if you happen to be searching for a site that you suspect has information related to Remote Sensing or GIS and cannot find it amongst such titles, you might want to look under Geography for instance. On the other hand different sites with a variety of purposes might be found listed as part of Government sites. After following the above tips, if you find a site that you think is lised incorrectly- wheather by way of being under an incorrect title or by way of being more appropriate for a totally new category, please

ILLOWA CHAPTER Dear GIS Professional: As you know, sharing spatial data with multiple organizations or departments means one of two things. Either considerable funds and time are needed to develop translators to facilitate data sharing or an agreement must be mandated to only use the same software and data structure. The Open GIS Consortium (OGC) has a more real world solution. The OGC develops interface specifications and transport encodings that improve interoperability with new and existing GIS implementations. The Illowa Chapter of GITA cordially invites you to participate in an informative seminar on OpenGIS. You will hear first hand what Open GIS is, what it does and how it can relate to Homeland Security issues for GIS professionals. Also featured in the seminar will be Robert Krumm, Geologist/GIS Manager for the Illinois State Geological Survey and President-elect of the Illinois GIS Association (ILGISA) as well as Kevin Kane, Director of the Iowa State University GIS Support and Research Facility and Chairman of the Iowa Geographic Information Council (IGIC) or other IGIC representative. They will provide an overview of their respective organizations and insights on the current state of GIS and data sharing projects in Iowa and Illinois. OpenGIS CONSORTIUM AND HOMELAND SECURITY Tuesday, June 24, 2003 - 8:00 a.m. - 3:30 p.m.
