Is there a way to calculate the mean elevation of a polyline?

Hi there,
As a part of my master thesis I've mapped from several years, the transient snow-line of a large Norwegian glacier, which relates to the health state of the glacier. I have a a high quality DEM over the same area, my question is - is there a way to work out the mean elevation of these polylines I have created? I tried creating a 1 metre buffer for the polylines, hoping to convert it to a raster, reclassify the values to 1, and then multiply using the raster calculator by the DEM. However when I try to convert the buffer polygon to a raster, the entire area that is enclosed within the polyline (the polyline is circular around the whole ice mass) is converted instead.

Could anyone help?
