My second climb of Bierstadt, Donna's first, Jake's first 14er.  This was in June 1999, or maybe early July.  There was still quite a bit of snow in places, lots of snowfields to cross.  So, first you have to go through the willows from Guanella Pass.  They stink.
Big thick tangle with lots of water and mud underneath.  My boots kept my feet pretty dry on the way up.  And we kept Jake on the leash because he was so excited, I hoped to conserve his energy by not letting him run all over.  There was a group doing trail maintenance in the willows, I thought that would be a nice way to volunteer someday.  We made it through the willows and let Jake off the leash.  He had a great time, running 10 times as far as we walked easily.  He got kinda cold farther up, since his belly was touching the snow in a lot of areas.  I tried to dry him off a couple times - maybe he needs a jacket of some kind.  Pretty uneventful climb, made decent time to the summit. Jake hit a wall of sorts at around 13,000' or higher, then he just trotted along with us instead of chasing after every bird and pika he saw.  We reached the summit ridge, and I put Jake back on the leash so he wouldn't edge out on the cornices on the east side of the ridge.

On the way back down, Jake barked at one guy he met, everyone else he didn't care about.  Funny how dogs just don't like some people;  I think they sense subtle signals of fear and react.  Oh, we slid down a lot of the snowfields on the way down, my nylon pants worked well for that.  I really have to get some better pants for climbing, though, since these don't breath and slick nylon pants are known as "death pants" since they'll shoot you right off a cliff if you fall.  Feet were thoroughly soaked after the snow sliding, so we just slogged through the willows not caring where the feet went, and made much better time.  Dry socks went on back at the car.
