To celebrate the National Park Service (NPS) Centennial the Geological Society of America shared three posts on its Facebook Page about programs run by GSA and the NPS. It recognized its Geoscientists-in-the-Park Program, which is part of GeoCorps; its GeoTeachers Program that provides K-12 teachers with enriching field experiences in national parks; and for NPS' role in the development of GSA's EarthCache Program. There will be several sessions at the GSA Annual Meeting in Denver on how to "Find Your Park" including: “T27. Find Your Park (and Other Public Lands) One Internship at a Time: Two Decades of Providing Career Development Opportunities in Public Lands for Students and Recent Graduates” oral and poster sessions, and “T71. A Centennial Celebration of Geology and Hydrology in the National Parks: Research, Mapping, and Resource Management” that will have two oral sessions (http://bit.ly/2bDVNzR) (http://bit.ly/2c422Py) and a poster session. Don't forget about the the International EarthCache Event Saturday, September 24th at the GSA Annual Meeting, or the EarthCache Focus Day during Earth Science Week.
