I've tackled 5 tame summits with my wife, who has MS. Guadalupe peak, the highest point in Texas and two other 8000ft peaks the same week were the first 3. Then just a couple weeks ago, we tacked Wheeler Peak, the highest point in New Mexico as well as stoping by Mt Walter on the way. Wheeler peak showed me that she was capable of more than I gave her credit for. It was a 100% alpine environment, we didn't see a single other person on the mountain and even took a small steep slope making kick steps with trail runners while using trekking poles as you would an ice ax!
So proud of her and she absolutely loves it. On July 11, we'll be heading up Mt. Whitney (assuming we get a walkin permit) and spending 5 days instead of the usual two (we have the time and she enjoys the slow acclimation)
I have no doubt she'll succeed on Whitney since it's such a cakewalk compared to her time on Wheeler (especially given 5 days!). My question is this. What would be a good summit to tackle after Whitney? Heat exacerbates MS, so trekking in 90+ is usually out of the question although we've had some success with a spray bottle for constant evaporative cooling along with a soaked cotton shirt. She would like another altitude milestone, which means it will be outside of the contiguous US (since Whitney is the highest). She would like to avoid crampons/ice ax and snow shoes if possible, but not a deal breaker. Scramnling for short stretches is fine, but any technical rock or ice climbing is a no go.
Thanks in advance for your recommendations.
