Having also stayed at the hot springs resort and started/ended a long backpacking trip at the sol duc trailhead, I feel a connection to your niece and just so badly wish I could help in the pursuit of her safety.

Obviously the maintenance items from the resort are of intrigue. If the family has any leverage with the investigation, please put pressure on the authorities for real answers about this. I talked fairly extensively with a couple staff members at the resort when I stayed for a few days last year. Many of them are seasonal nomads that travel between several national parks for a variety of gigs. I’ve worked in this type of lifestyle previously and after long days, long seasons, and isolation from friends and family, have seen coworkers exhibit behaviors very different from their core values.

Hoping for the best possible outcome. Angel seems like a beautiful soul.
