All Time Resort Run Views, personal heatmap

In the all time Ski Resort View for yourself, you see the map of the resort above, I think it would be cool to either see ther all runs combined in the map, or be able to generate a personal all time/ seasonal Ski Resort heatmap of all the runs one person has done in that resort, and to see which areas could be explored more closely, kinda inspired by your published heat maps for popular resorts!
