NPS National Historic Trails Site

A reader sent a link to this site and I thought it would be of interest to all of you. This site, produced by the National Park Service (NPS), has detailed maps showing the routing of various national historic trails. Of interest to California, it shows the National Old Trails Highway (US 66), El Camino Real (US 101 for the most part), Old Spanish Trail, and a few others. Come check it out!

Bicycling Guide – Caltrans District 9

Caltrans District 9 – Covering Mono and Inyo Counties as well as a portion of Kern County, has come out with a new bicycling map which details many of the routes in the region and alternates to roads closed to bicycling. The region is a great place to ride when the weather is conducive. Just beware of high winds and high heat at times.

Geology Phone App

There is a very cool phone app I have been using for a while. It is called “Rockd” and has access to geological maps and information throughout the US. In addition to the maps, it also has references to the sources, which is very helpful for geologists. Think of it as a geological map for anywhere you go. There are social aspects to the app as well, which can be fun, but I still find the maps and data to be the best. It is available for both Android and Apple phones. It is also free, developed by the University of Wisconsin. Try it out!
