• [ ] Elevations need to be retrieved for each point on the path
• [ ] When an adventure path is saved, the highest and lowest points on the path need to be saved along with the distance
• [ ] Figure out what turf chunks are
• [ ] Get a graphing plug in
• [ ] Definitely figure out a good way to save the z coordinates of each point along the path when the path is saved
• [ ] Graph the z coordinates in the graph
