I love to hike, backpack, and camp. To me, there is nothing more refreshing than a couple days out in nature, away from the hustle and bustle of the city. Recently, I spent my Labor Day weekend hiking in an area new to me. My husband and I did some research and decided on Crater Lakes Trail, near Nederland, CO. According to AllTrails.com, the out-and-back trail is approximately 2.7 miles one way, and it climbs in elevation the entire time, giving it a rating of hard. We were up for the challenge!
AllTrails provides nice contour maps for planning your hike, but as someone who was unfamiliar with the area, I wanted to see just a bit more about my upcoming trek. I downloaded the GPX data for the trail we were going to hike and the surrounding trails. In Surfer 13, I used the Grid | Mosaic command to extract my area of interest from the Surfer sample file Colorado.grd. Using the methods outlined in this article, I converted my paths and grid file from latitude and longitude to feet. I created a profile from the grid file and the path and assembled my maps. I overlaid base maps, a post map, and a contour map for a 2D view, and I also created a 3D surface map to get a better idea of the topography. You can see the results below.
