First, use four similes to describe the lake: Grinnell Lake is like . . . a threshold . . . a turquoise . . . wings arching open . . . a nest.
+++ At the end of the boardwalk over red-rock streams, beyond the suspension bridge, the waterfall, the long hike, my feet on fire empty into the lake: home. Icy aqua iridescence, perfection of mountains, these trees.
Now use four metaphors: the lake is . . . reality . . . exquisite balance . . . a window . . . a cup filled with sky.
+++ In the lobby of the grand hotel miles below hang beautifully framed old photos. Grinnell Glacier, a wisp above us now, was enormous a century ago, its lake many times smaller.
