Trouble interpreting layers of fire history on CalTopo

CalTopo’s fire history layer is a nice feature for those of us who hike in fire-prone landscapes. The difficulty I’m having is teasing apart different layers of fires to determine which outline belongs to which label. This is important because I might have no qualms hiking through an area that burned in 2013 but I might not want to hike in an area that burned in 2020. The fire perimeters are clearly delineated but when you have areas that have burned more than once it becomes difficult or impossible to tell which label belongs to which fire. Anyway know if there’s a way to do this? Thanks.

I think that the colors are time connected, so the darker the color, such as deep red, equals more recent fire activity.  There should be a color key in the lower left hand corner of the map.

Thanks, that helps a bit. It’s still hard to read if you’re looking at, say, southern OR. I wish it were sophisticated enough that you could select polygons in the layer to highlight them, or at least that the labels followed the color system as well. Or maybe we just need fewer fires…
