Map of Angelica Couloir route. The blue is the route of approach to Lake Patricia. The red is the route from Patricia Lake up Angelica Couloir. The yellow is the variation I took. For more photos from my Holy Cross trip check out my website: www.leachfam.com.
This map shows a non-standard route that require some off-trail navigation. If you find the correct trail from the maintained Half Moon Pass Trail up to Lake Patricia it's not too bad. But if you don't get on the faint trail then the navigation can be a bit difficult and the terrain rugged. From Lake Patricia to the summit the navigation is pretty straight forward.
The north ridge is considered the standard route and I believe it is fairly obvious (though I haven't done it). I think the big challenge there is on the way down you need to make sure you head east at the correct point so that you get into the East Cross Creek drainage. It seems like several parties every year wander down into the Cross Creek drainage, get lost, and have to be rescued. Click here for such a story.

"Never! Never, Marge! I can't live the button-down life like you. I want it all: the terrifying lows, the dizzying highs, the creamy middles. Sure, I might offend a few of the bluenoses with my cocky stride and musky odors - oh, I'll never be the darling of the so-called city fathers, who cluck their tongues, stroke their beards, and talk about what's to be done with this Homer Simpson?!"
