The Power of Historic Topo Maps

When it comes to map layers, those, I think, are really powerful tools within on X. The other one that I use a lot is Gaia. It has a huge suite of layers available to it. And some of them can be stacked on top of each other to show additional detail. They actually have started to make available historic topo maps. So there's one from maybe 1904 or something like that. But these old topo maps are just awesome, because they're hand drawn and also have cartographers notes.
