Immediately below "The Big Pool" there is another well defined rapid which begins a stretch of continuous boulder garden rapids (Class II-III at 2.6-3.0', Class III-IV at 3.0-3.6', Class IV until you get to 4.5' then Class 5-ish) that keeps up until just above the railroad bridge.
The initial drop consists of a 10-15 yd lead-in (class II) which leads you to a 2-3' ledge. The main flow is on river right (though a left line develops at about 4'?) and consists of a vertical drop into a fairly deep and fluffy hole. The ledge is curved with the center upstream and the left and right sides downstream. Generally I have boofed off of the rock on the right side of the main chute. Running straight down the center or left side of the main chute will give you a good meltdown. This Hole is at it's worst from about 3.0-4.5'. If I remember correctly, that's when it begins to become less "steep". About 15 feet downstream of the first drop there is a very small ledge (6"?) which creates a stickier than you'd think hole at 2.6-3.5' or so. Scouting this drop is easy from river left.
The next 50 yds consist of the continuous Class II-III boulder garden rapids mentioned before. These lead to a more defined "finish" rapid.
