Frequently Asked Questions

How do I download a topographic map?

Where can I find elk on topo maps?

Benches, fingers, bowls, basins, and wallows are elk hotbeds, and certain topographical features will tend to hold more elk than others. For this reason, a topo map such as onX Hunt’s Topo and Hybrid Basemaps can be your first step to finding timbered-up elk. Learn more at Using Topography to Find Elk with Remi Warren.

What is a saddle on a topo map?

Contour lines will form an hourglass shape with rising contour lines on each side. Learn more at How to Read a Topo Map for Hunting: Contour Lines, Cliffs & More.

How do you find relief on a topographic map?

Relief is the amount of topographic change in a given area. Specifically, it is the difference in elevation between two points, which can be calculated on a topographic map using contour lines.

What are the three types of contour lines on a map?

“Index Lines” are labeled with a number representing elevation above sea level. These are the thickest lines on a topo map. “Intermediate Lines” are thinner and appear between Index Lines. Generally, there are four Intermediate Lines between every Index Line. The elevation between Intermediate Lines is typically found in map keys. “Supplementary Lines” are used to indicate flatter terrain.
