How to identify topo-map features.

This is kinda in a nutshell, but hopefully this can help some of you who aren't very familiar with topo maps.

Good stuff! That will really help many visualize exactly what they are looking at! 8-)

I know for sure military-grade topo maps mark elevation in meters. Does anyone know if civilian-grade topo maps mark the elevations with meters or feet? That might cause some confusion and wanted to clear that up.

I always thought they were all measured in feet... I might need to look closer at the map legend next time I read one.

I am clear on everything except... what is the difference between "marsh or swamp" and "submerged marsh or swamp"? The map symbols look quite the same to my brain?

It will tell you in the Legend. Also, remember there is also a contour interval. The index contour line will give you the elevation and the intermediate contour lines all have a specific interval in between them. Usually 10-20 feet or meters. This is a good way to make a range-card for your hunting tree.

The pic is small to tell, but the submerged marsh square is filled in with light blue with the little blue lily pads and the regular marsh is white with the blue lily pads.

Dan, might be a dumb question? But what do you mean by range card?

Feet. Nice short, clear easy to understand tutorial Crazinamatese. I'm sure it will help many members. 8-)

In the Army Infantry, we would draw a range card of your sectors of fire when we set up a patrol base. distances, obstacles, fields of fire and so on. Its not a hunting term at all. I really don't sit and draw a range card while hunting either, but I will zap distances with my range finder and use things as range markers too. I will keep that mental note in a way that I just refer it as a 'range card'. Anyways, using the topo map and counting the intervals on the intermediate contour lines and index lines, if I know where a buck bed is, and use a topo map to guess the distance from where I could set up, or get an idea of why that buck is at that elevation without getting in there and polluting the area. Its something I really never thought of until recently. I just need to make sure the map I use is legit.
