Enjoyed the TR and pics. Glad everything pretty much held together for your trip. Miter Basin is splendid. My first visit to Whitney was via Miter Basin, the sandhill, and over Discovery Pinnacle in 07. Everyone should try this route.

We followed the left branch of the inlet stream that feeds SBL. We were aiming for lake 12129 but got a bit off route and wound up on the high ground between lake 12129 and the lake shaped like Africa at the base of Mt. Newcomb. This turned out to be not so bad. It was an easy traverse over to lake 12129 where we camped. On the retun leg of the trip we traversed around the Eastern shore of lake 12129 and Harvey is right. It is quite rocky with boulders the size of coolers up to washer/dryer size. Some of which moved a good bit when you stepped on them. Be safe and hope you have an awesome trip.
