I use it all the time. Free and accurate to match a followup physical recon of the area. Just because it looks good on the map does not mean it is from the ground level. It is a tool and a way to build custom maps and waypoints to major terrain features / grid locations / lat / long to match ground recon. A map recon allows you to see the larger terrain environment for water resources / habitat / elevations / blocking terrain features and setting them up to use these to your advantage to follow up with later ground recons to proof it.
You can right click and copy on google maps and paste them in on MSPAINT to make custom maps and annotate waypoints on terrain features, add a scale legend, etc to print out or take you or save and print at Walmart and blow the image up in size to have a nice custom inexpensive desk/wall map of areas in different view formats from satellite, terrain, topo of your hunting area. It also shows elevations for precise crosshair elevation readings on terrain features or whatnot you want to move them on to make terrain associations for your gps when you are on the ground recon and want a ballpark reading to that feature to see where you want to set in at or use the terrain to your advantage.
Ice Lake Basin Topo Map
topo map with crosshairs for gps co-ordinates and measuring distance
example crosshairs on Clear Lake :
Center: UTM Zone 13 254766E 4190220N (Clear Lake)
Elevation at center: 11,975 feet (3,650 meters)
Copy and past the UTM data for a waypoint for Clear Lake or assign it a number
on the map and at the bottom of the map you are building with MSPAINT annotate the data for the landmark / feature in a legend off the map. Yellow numbers usually work best over a green background.
It takes very little time on constructing a base template map and then annotating the template how you wish for your own custom larger map for hunting / pack hunting / wall display / desktop large study overview planning routes / set in points / after proofing with ground recons.
It is pretty nice to have tools online to manipulate to your advantage on planning future hunts / pack hunting trips, etc.
