its all pretty rough in there..especially with all the rain we have been getting...lots of good sticker bushes out thereVomiting is a sign of dehydration. Make sure you both hydrate plenty- not just water but electrolytes. Coconut water is good.
Been up Peter's Canyon a couple times- fun hike, but believe me, that's nowhere near the roughest country you can find in the Supers. If you took the lower portion towards Pistol Canyon, it runs alongside Malapais. Did you see the large "Peralta headquarters" cave on the right hand side?
Anyway congrats on your hike into the Supers. I just love being out there. Beautiful country.
