- Red supergiants (RSGs) are stars with a supergiant luminosity class (Yerkes class I) and a stellar classification K or M. They are the largest stars in the universe in terms of volume, although they are not the most massive or luminous. Betelgeuse and Antares A are the brightest and best known red supergiants (RSGs), indeed the only first magnitude red supergiant stars.

Denny Creek sports a number of waterfalls, some quite a bit more noteworthy and conspicuous than others. Keekwulee is the most significant of the bunch and is one of the prime attractions along the Melakwa Lakes Trail near Snoqualmie Pass.
