Map: Thunder Mountain North

Thunder Mountain Map Sample

Hillier terrain with larger contour features and smaller pockets of contour detail. Very similar vegetation to Kelowna Nordic Core, but with sections of very dense forest that drive route choice decisions in otherwise highly runnable, white forest with no deadfall. This terrain features scattered rock features and marshes, with a low to medium density trail network.
