Ice caps are not constrained by topographical features (i.e., they will lie over the top of mountains) but their "dome" is usually centred around the highest point of a massif. Ice flows away from this high point (the ice divide) towards the ice cap's periphery.

Vatnajökull is an example of an ice cap in Iceland. [cite journal
