Summer bouldering suggestions

My boyfriend and I are doing the van road trip thing this year. So far we've been doing a lot of sport climbing, but we'd like to do more bouldering. Right now we're in Ten Sleep and would like to stay on the western side of the country. Not planning on heading back east until the spring. Are there any bouldering areas that aren't sweltering hot right now? Suggestions so far have been:

RMNP
Leavenworth, WA
Tahoe
Lander, WY

Where should we go for some good bouldering and to escape the heat? Preferably some place with free or cheap camping. Or are we wasting our time and should just stick to the cooler sport crags until the temps drop?

If you have your passports then squamish all the way! Way cooler than Leavenworth.

Burst Rock features in this relevant Climbing Magazine article.

Camping will be problematic at RMNP.

Leavenworth will be hot. Index/Goldbar on the west side of the mountains will be better or better still Squamish.

tuolumne meadows
way lake, mammoth lakes

for some coastal breezes
sonoma coast, ca
lost rocks and houda point, humboldt, ca

Thanks for the replies. I figured camping in Colorado would be a hassle. I think Squamish is our best bet.
