In order for a glacier to form, there needs to be a consistent accumulation of snow that exceeds the amount that melts. This is why more snow needs to fall in the winter than melts in the summer. Over time, this snow will compress and turn into ice, eventually forming a glacier. While elevation and temperature can certainly play a role in this process, they are not as critical as the consistent accumulation of snow.
