Amaranth is located on the SW side of Plumb Line Crag. It is on the lower tier of the Crag. It is located about 100 feet to the left of the distinct Plumb line hand crack, and is about 40 feet left of _Barley_. The climb follows a thin crack up a left facing corner. The crack widens at the top, but does not require any off width climbing. You will need to boulder about 10 feet up to a ledge at the base of the finger crack. Beware of a thorn bush on the ledge, and beware of a potentially loose block if you scale up on the right side of the ledge. The block is balanced on its end, and you don't want to yard on it and pull it down onto your partner. Setup the belay in some large boulders perched on the Crag's middle terrace.
To exit scrabble off to your right (East) staying high on the terrace until you are on the East side of the Crag. Alternatively, there are bolted anchors on the large boulder just above the Plumb Line crack that can be used for a rappel.
Protection
Light rack with small-to-medium cams. A #4 Camalot will protect the last move out of the wider section at the top.
