The Prospect Hill map (1:10,000, 5m contours) has been updated to LiDAR-based contours, International Specifications for Orienteering Maps (ISOM) 2017 standards, and fully re-field-checked in April 2019.  The updated map is considerably "greener" than the previous version, reflecting the reduced runnability of portions of the forest due to undergrowth, and the LiDAR data provided the opportunity to better depict the many subtle contour and rock features that this park offers.  This park sees many users, and the smaller trails change over time--come enjoy navigating on the updated map, while it's fresh off the presses!!!
