With well over 50 species of plants in the Snake River Canyons Park, plan to come out and see what you can find, like the Sego Lily or the various types of milkvetch. There are several types of lichens which color the lava rock outcroppings. Sage brush abounds, and with two different types you can challenge yourself to tell them apart. You’ll find trees located down in the canyon where there is more moisture while the smaller more drought resistant plants prevail up on top.
