The creek is actually crossed by a logging road bridge between the two tiers.
[1] Ashlu Falls stands a total of 33 feet in height.
The upper drop is about 10 feet high & its width is over 10 times its height.
The creek then flows under the bridge & bends before then dropping another 20 feet or so through a narrow chute into a deep pool.
On the north side of the lower drop is a large section of sculptured rock that, when the creek is high, is completely covered with water, making the lower tier roughly as wide as the upper tier.
