Climbed at Vantage last weekend. It is basalt columns. Unlike Table mountain it seems they only climbs on the columns and pass on the chossy face above. There are areas where it looks like if someone went in top down with a pry bar some good climbing could be unearthed. The routes in this area a fairly well packed in so it is possible to lead one route and TR several others. Manged 2 5.8's, 1 5.9 and 4 5.10's, 10 pitches total. I only lead the 5.8's' and the 5.9'. Everything else was TR'd. Oh, the 10b TR was setup by a 14 year old girl. One of the 5.8's was really good, Twin Cracks on Sunshine Wall, I could do this route many times.
