The western slopes of Eldorado Canyon and surrounding Boulder Open Space hold a plethora of boulders and bouldering problems. These boulders have been climbed on for years, and knowledge about most of them goes back to the early to mid-90s. However, I'm sure some were climbed on earlier, as I've personally talked to many, many climbers from the 60s, 70s, and 80s who used to frequent Eldorado Canyon and the surrounding Flatirons to climb and boulder.
Down in the start of the Overlook...

The Overlook Boulder is located deep on the western slopes of Eldorado Canyon (technically, these are the western slopes of South Boulder Peak and its ridges). Sitting up on a hill side at the intersection of the Outback and Metaphysicals, the Overlook Boulder offers a number of fun, overhanging problems ranging from V5-V8.
Several variations: straight up (Tilde ~V6), right and up (Time Snap ~V5), all the way right (Blank Check ~V8)
Around the corner from the main face, a couple slab moderates exist on the southwest facing side of the boulder, plus some more fun moderates on the boulder located just across the small wash. Behind the Overlook is a large, house sized boulder with one very hard problem on its southeastern side.
