Exploring the Highs and Lows of Landscapes: Demystifying Topographic Maps

Want to learn more about Earth’s geographic features?  This workshop will focus on landscapes, their origin, and recognition of landforms on topographic maps.  The topographic map is the most common tool used by geologists, geomorphologists, geographers, landscapers, and land managers to identify landscape types. Topographic maps are also essential as way finders for people in areas that are not familiar to them. These maps represent a three dimensional surface (landscape) on a two dimensional piece of paper by incorporating contour lines that show points of equal elevation.  

September 2017 PAESTARs

This month we recognize brothers Devin and Roldan Kramer from Ardmore, PA, for receiving the 2016 President’s Environmental Youth Award for grade levels K-5 in EPA Region 3 for their work to save frogs and toads. The national award is presented each year to exceptional students who demonstrate creativity, innovation, and leadership to address difficult environmental challenges. The brothers’ interest in the topic was sparked by discussions about the number of mosquitos in their area, and the decline of predators like bats, frogs and toads, which feed on mosquitos.
