		+	Crevasse initiation is linked to strain rates that range over three orders of magnitude (0.001
		+	and 0.163 a–1) as a result of the temperature-dependent nonlinear rheological properties of ice and from
		+	water and debris inclusions. Here we discuss a small cold glacier that contains buried crevasses at and
		+	near an ice divide. Surface-conformable stratigraphy, the glacier’s small size, and cold temperatures
		+	argue for limited rheological variability at this site. Surface ice-flow velocities of (1.2–15.5)⌃0.472ma–1
		+	imply classic saddle flow surrounding the ice divide. Numerical models that incorporate field-observed
		+	boundary conditions suggest extensional strain rates of 0.003–0.015 a–1, which fall within the published
		+	estimates required for crevasse initiation. The occurrence of one crevasse beginning at 50m depth that
		+	appears to penetrate close to the bed suggests that it formed at depth. Field data and numerical models
		+	indicate that a higher interior stress at this crevasse location may be associated with steep convex bed
		+	topography; however, the dynamics that caused its formation are not entirely clear.
