|Landslides in Arizona
Posted: 04 May 2014 05:29 AM PDT
The Arizona Geological Survey has a new article by Michael Conway titled: Landslides – Mitigating a clear and present danger.
The Arizona landscape is no stranger to landslides. The entire spectrum of landslide types – debris avalanche, debris flow, earthflow, creep, rock fall, rock slide, topple, rotational and translational landslides – are encountered here.
|Guide to the Redwall Limestone of the Grand Canyon
Posted: 04 May 2014 05:25 AM PDT
Here is a really nice educational guide from the Arizona Geological Survey Repository. One of the best educator documents that we have seen.
“What makes the Redwall Limestone a unique and important stratigraphic unit in the Grand Canyon? This is one of the questions asked and answered in this guide to the Redwall. Written to assist guides in describing the geology of Grand Canyon, this colorful product should be of use to professional geologists, geophiles and people generally interested in geology.”

Mineral hardness picks are pencil-like tools that have points made from materials that match the hardness of minerals in the Mohs Hardness Scale. With them you can easily test the hardness of mineral grains in a rock and test the hardness of small-size specimens. In our opinion they are easier to use than pieces of minerals and allow you to obtain more accurate results. They also do not contaminate your specimen with particles of the hardness mineral.
