Do you have a source for these supposed glaciers? Even if they exist (I've hiked these areas extensively and I've never seen them) I am questioning the value of including them on the map as it's genuinely confusing since there the glacier on the map doesn't correspond with any visible feature to the user in real life. If they exist, it's a geological curiosity, sure, but the entire bowl is a gigantic boulder field and there is no apparent visual difference between the "glacier" section and the rest of it. You can't see any ice even down in the cracks between the boulders. You can't see any different in the types or sizes of rocks. There's literally no indication of where it begins or ends. idk. It's very very confusing to have this marked on the map when there is no visible evidence of it whatsoever even with close inspection in real life.
