key priority (but hopefully very simple)

Current status: @DanielJWood has researched some higher-res versions of the historical surveys. @rhersher is doing additional reporting (for example, to get a sense of what year(s) those surveys actually reflect.

We'll go with a viewport of the lake+glacier similar to the following:

Labels will be of the lake and the glacier. Can probably just do 2 to 3 stills of this.

up to you all how you do the graphic. It could be a gif, but maybe instead could be three slides, fading from one to the next to the next. From a technical standpoint, that would actually be higher fidelity and easier. You just need to do one export of the oldest map, one export of the 60s map, and one export of the satellite imagery from recently. I'm not sure how the copy is written at the moment, but it could be written to fit this.

It's sort of up to you if you think we need labels or vector outlines of the lakes to highlight them. I included a shapefile that has polygons i traced of the different lake sizes.
