WA State 50-100 mile loop

On July 1st my daughter and I would like to do a loop. I am moving her from Richland WA back to Indiana. We got reservations for the Wonderland trail a month ago but now we understand its under snow so we thought the Wenaha-Tucannon Loop but its under snow. I want to backpack not base camp and daytrip for a week. We are both in decent shape, ok she's in great shape and I manage thanks to an 8lb base weight. Can you'all help.
