The Last Tributary

A fitting finale to the development of this sector, The Last Tributary diverges from Aqua Augusta at bolt six, forging its own  path up a blunted arete. As the most difficult route in this sector, it demands precision, confidence, and a willingness to commit when the way forward feels uncertain.

From the branch point, trend upward on easier terrain until reaching a sloping and horizontal seam. The path above this seam will demand trust in marginal footholds, balance and tension, and long moves A brief reprieve follows before the route presses upward, navigating the exposed arete to the final bolt. This guards the route's true test: a committing slab crux over a bulge, where reading the subtle features and trusting hard-to-see feet become essential for success. Push through, and you’ll find yourself standing atop the proudest line  The Aqueducts- Upper Tier.

True to its name, The Last Tributary is a fun and demanding addition to the Colosseum's "waters", likely representing the final development of this entire area.

Start off the "summit" ledge at the same anchors as "Aqua Augusta". Climb the first six bolts and then traverse slightly left and up to the blunted arete. 

5 bolts after the branch off of "Aqua Augusta", or 11 in total. The route ends on SS quick lower biners which will get you down to the "summit" ledge.
