With CCS/CHAdeMO QCs in Aspen, they'll obviously have to provide some to reach Denver, SLC and Vegas via I-70, plus connecting to the existing QCs along the I-15 corridor in the near future.

I paraphrase the entire build-out as a presumption that trips over ~ 200 miles each way will not be with an EV.

I don't think that's the plan, just prioritizing the major traffic routes first. Having joined up numerous city pairs, it's fairly easy to build a few more QCs as connectors between those points. And don't forget, they do plan to complete I-5, I-95 and I-80 east to 76 to 70 to 15 very early. Tesla did the first two (more or less), but their initial transcontinental route was anything but sensible.

That is what I mean -- allowing ~ regional travel.

Not for me in SW Colorado of course, but in the megaplexes.
It is a fair roll-out ... for EVs as second cars.

Add in some snow or a single accident and it is just not feasible. The ups and downs across I-70 from the front range to summit county will zap your range. Then get stuck in a traffic jam for 3 hours in subfreezing temperatures with slush and snow all over the road, and EVs will be littering the shoulder out of range. That was one of the most expensive pieces of interstate and challenging to build. I don't know why you'd start with that to build out infrastructure.

Also all the DCQC around here are limited that I've seen. I have never gotten more than 30KW out of the Nissan chargers. And with freezing temps and high elevation, the units limit their output.

You did note that EA's plan will have average QC spacing of 66 miles, with none of them more than 120 miles apart, which is better than Tesla is doing at the moment? Certainly you wouldn't want to set out on a long road trip in a 1st gen affordable BEV in winter conditions in the mountains, but that's just common sense. A 40kW LEAF might be pushing things, but a Bolt or 60kW LEAF should be fine, especially as the ski areas add L2.

The necessary locations for QCs on I-70 over the Rockies are pretty much obvious - just look where Tesla put SCs and infill a few more. Grand Junction and Glenwood Springs (87 miles) are no-brainers, and you probably want one either side of Vail Pass or Eisenhower tunnel as well, say Vail (61 miles) or Minturn and Dillon/Silverthorne. Each with have 4-10 stalls (for starters), and you can expect infill between those (Rifle, Eagle, Wolcott, Copper Mtn., Empire etc.) and Denver as demand increases.
