In two dimensional space, Rosenbrock function has a long ravine with very steep walls and flat bottom; “because of the curved flat valley the optimization is zig-zagging slowly with small stepsizes towards the minimum” (en.wikipedia.org/wiki/Gradient descent).

Between two consecutive peaks, there must be exactly one ravine, so having k + 1 peaks is equivalent to having k ravines.
Bijections from weighted Dyck paths to Schroeder paths
Any ravine can clearly be “filled in” and replaced with a horizontal step, so a Dyck path with k ravines corresponds to 2k little Schr¨oder paths, which explains equation (1).
