The number of tiers for each waterfall is listed when it is available. Ideally , a tier consists of a free-fall water drop, beginning when the water leaves the bed of the river or contact with rock and ends when the water hits rock or the bed of the river again. However, in practice the number of tiers is often hard to define, which also makes precise definitions of a waterfall's height and form generally impossible. We'll call that a single-tier waterfall here, since that is what it looks like. Also, a multiple-tier waterfall with many small tiers becomes a waterchute or simply a steep stream, and hence the boundary between those forms is imprecise.
Many waterfalls combine both a chute and a single or multiple tier.
Since Brown has ranked 200 waterfalls in California, and this puts them in the top 62 of the 200, we clearly have some waterfalls worth seeing. However, be warned that our spectacular waterfalls have a short season, and may be much less than spectacular the rest of the year. Yosemite of course has a lock on the waterfalls rated 10 by Brown for good reason. Yosemite's waterfalls are much higher and have much more water flowing in them. Our best waterfalls are typically 50-100' high.
