This lip traverse is friction dependent and usually chalked up. Sit start under the roof on a good flake. Move R hand to snag a sloper on the lip, and either use an undercling or slap L hand up onto a sloper around the lip. Traverse left, utilize a heelhook, then head up the arete/jugs to the topout.
This boulder is across the stream near the problems Kalbro & Ceadas. Walk past EZ Cheese to the stream and the chalk is usually visible.
