Horsetail Fall (Yosemite) picnic area on the north road leading out of Yosemite Valley east of El Capitan. Horsetail Fall (Yosemite) Horsetail Fall, located in Yosemite National Park in California, is a seasonal waterfall that flows in the winter and early spring. The fall occurs on the east side of El Capitan.

This natural phenomenon is often referred to as the "Firefall", a name that pays homage to the manmade Firefall that once took place in Yosemite.
Sequence feature variant type the conserved nature of the functional regions and the precise change in the actual amino acid, the Sequence Feature Variant Type is defined. A sequence feature is basically a collection of amino acids within a protein, where the collection may be a continuous range or some discrete residues. Most sequence features are from experimental results, but there are some that are from computational analysis. For each sequence feature, the variations exist between many proteins from different related species. The variant types define the exact amino acid at each location for a feature. The larger the mutation at each location for
