Great job with the rescues, the Whitehorse crew anchored themselves so that was a climbing trip also.
The Washington one appears to be the 'take a non-hiker to the biggest mountain around,' not entirely uncommon. (not the hardest but it's still a big walk on a trail that is nothing at all like a rail trail or sidewalk)
If you wanted to introduce a SO to hiking & how enjoyable it is (you take your old High school chums out on a I'm still tough trip & you guys are sofa spuds trip - okay thats dumb too, take your daughter's bad boyfriend & when he pulls up lame ditch him, literlaly push him in a ditch or ravine
) Anyway the point is why take a SO to Washington for her first hike?
Something with a view, some cascades, maybe a bathroom (hut) & relative peace & quiet that's enjoyable not blister & profanity inducing.
Zeacliff, Moosilauke from the Lodge, Pierce, Osceola & a bunch more make more sense.
What was the weather like & time of day did he descend auto road? out at 3:30 AM must have been late. if the weather was not bad & early enough, ascending would have been quicker to get SAR troops up from the vague picture I'm coming up with for where she was. (up Tucks, they assisted down Chandler Brook makes me think she was above the headwalls along the Alpine Garden Trail or off trail completely.
Of the three rescues, two were for making less than good decisions (hard to pin Cannon Rescue on decision unless purposely off route & planned new ascent on bad rock) One was too much hike for a non-hiker & other was for starting too late for the group to complete the climb assuming it was not too much for them.
