I was in the southern part of the park last week, and the snow is in fairly small patches now up to 10K feet with 5% to 10% coverage, so I never got to use my crampons. Many of those patches are still fairly high and often are snow bridges over the trail, which is sometimes turned into a small runoff stream, so you may need to leave the trail and go around them. Make sure you tackle areas with snow early in the morning when it is still hard. I had to hike most days from 7 am to 1 pm due to the heat, which just exhausts me. 75 to 80 degrees F at 10K feet is too much for me. Since there is no tree cover in those passes, that would be my biggest concern, running out of energy and needing a ton of water.
Expect to be greeted by swarms of mosquitoes when you drop down to Benson Lake. They are starting to get bad now at 9K feet, so I can only imagine what they are like at 6.5K feet.
