This climb starts just right of the obvious thin crack towards the left side of Lower Tier and continues straight up and a bit right to a large stance below the upper wall section. Getting to this stance is not too difficult technically but it is a bit of a runout. A small cam could help protect this part. Move right a bit to another bolt and head straight up to the top. I believe this is the crux and is definitely runout. Easier climbing to the top is found if you move right and then up although this probably in not correct as the double anchors are straight up.
