    I'm thinking about using the relative elevation value to alleviate that. Select by altitude to get the high points, then modify the selection to a distance selection. Create a selection of the low points on the relative elevation grid also modifying this to a distance selection.

    Add the value of the first selection to the second selection multiplied by a weighting constant. If the threshold and weighting constants are well selected, then I think you'll wind up with high areas selected and channeled areas surrounded by higher ridges selected to a lower altitude. At lower elevations, snow will tend to cling to protected basins.

    Edit: Looking back at it and earlier versions, it might also help to take slope into account, although slope and relative elevation have to be related.

    Edit1: Didn't work...
