As an archaeologist, we spend lots of time in the field in isolation. Which gives us plenty of time to listen to the latest podcasts!
The National Trust for Historic Preservation (NTHP) just released an awesome list of podcasts. The NTHP is a great organization, and we highly recommend getting a membership! Membership includes the Preservation magazine as well as discounts to museums and historic hotels.
Our PanGIS Staff has a couple of favorite podcasts that made the list.
