Slope of Land

I tracked the elevation of Mt. Hood in Oregon. I used increments of .5 miles since Mt. Hood is not a very highly-elevated mountain. To make a path I used the icon that looks like a couple of lines connected by dots. I would draw the line from my starting point to the distance from that point that was equal to .5 miles. I would then put a place marker (yellow) at the .5 distance. I kept tracing paths from my previous place markers that were .5 miles long, then delete the extraneous paths once the place markers were put down.
