Shooting star
Isa Lake on the Continental Divide west of West Thumb has a splendid covering of
yellow
or
Rocky Mountain pond lilies
(Nuphar polysepalum),
as do several ponds around Norris
Junction. Native American Indians roasted the large seeds and ate them like popcorn, and the
rootstocks are food for muskrats. Pond lilies are pictured on
pages 43
and 108.
Yellow composite flowers are many and hard to distinguish. Two common ones that have
distinctive leaves are
heartleaf arnica
(Arnica cordifolia)
and
arrowleaf balsamroot
(Balsam-
orhiza sagittata).
