Is it a round crater or more like a gouge? You'd expect a low and slow glancing blow would leave a big gouge through the soft crust.

All of the Earth craters fit a model regarding the ratio of crater width:penetration depth. On the moon, the smaller craters fit the model perfectly but the larger ones are way too shallow for their width.
