4. Llano to FM 3404 (below Llano) (19 miles)

Pink granite is a sight not often seen in Texas, which is why the rivers and creeks that cut through the Llano Uplift, a granite vein running roughly from Fredericksburg to Burnet, are a rare prize.  The Llano, in particular, is a very wide river, but because granite doesn't erode as quickly as limestone, some of the rapids on it are surprisingly technical.  Above 10,000 cfs, the river starts to behave like a big water run, generating some Grand Canyon-sized features. Since whitewater paddlers most often put in at Long's Fish Camp to run the falls, beta is needed on the stretch above this.  Difficulty rating for that stretch is taken from Texas Whitewater.  Distances and gradient measured using GIS tools in 2015.  Maximum gradient is 30 fpm, measured from Don's Fish Camp to the base of Long Falls (0.5 miles.) This drone footage shows The Slab, Eagle Rock, and Long Falls at thousands of cfs (exact level unknown, but probably between 3000-7000 cfs, based on the gauge readings on the day it was shot.) For scale, the river is well over 100 yards wide at Eagle Rock.
