Thursday Night at Camp IV (see the map below).
Trina sent some video from Camp IV where she is spending the night. This is a little more than half way but the second half is more vertical and more technical causing slower progress.
40% change of rain tomorrow morning, so they may have to wait that out, but they are prepared for it.
The next major feature is “The Great Roof” which is like it’s name says, a huge roof that they need to climb out and around. Trina says it looks pretty intimidating from where she is now below it.
If all goes well she should summit on Saturday and do the 6 hour hike down on Sunday.
