Mostly aid for us. Done at about 9+ C1 (C1, C1, 5.9+ C1, 5.8 C1). Burns guidebook for this line is total misinformation. My fault for not checking other guides first. Last pitch (which is NOT 5.8 face....crux is more like mid 10's face on Entrada sh..) is now protected by one half-way out peg. Above, run it out (~5.8-ish) to the summit. Would recommend this only as a peak bagging type outing for those not comfy on freeing mid-11 on Entrada. TR here.
