Take a virtual hike with avatar bird Brownie to learn about the environmental changes that occurred in the Lehigh River Watershed in Pennsylvania during the past two centuries as a result of the zinc smelting plant operation at the Lehigh Gap.  Explore a series of 360° photospheres that contain interactive features to learn how a green mountainous ridge was transformed into a barren “moonscape” and how the area has been revitalized today. This program is for ages 10 and up. Registration for a 30 minute time slot is required.
