Is there a difference in result depending on using snow or ice?

Is there a difference in result depending whether you use snow or ice? To answer this question I dyed two 0,5 yard pieces of cotton fabric, one with snow and one with ice. The fabric was soda soaked and rubber bands were tied around pinches of fabric. Each fabric was put into a separate container. On one fabric snow was packed, on the other ice cubes. Approximately 0,25 cup of Chocolate Brown (Dharma) dye powder was sprinkled on each pile. The containers were left in the studio till the next day. This is how they looked after the snow/ice had melted.

I forgot to take pictures before, sorry. The fabric was marked with a black Sharpie in a corner of each fabric. Unfortunately the dye covered the marks completely. Lesson learned. If you want to be able to read your marks after dyeing, use a small piece of Tyvek instead of writing directly onto the fabric.
The next step was to remove the rubber bands and to rinse, wash and iron the fabric.

The top one is my favorite, but is it dyed with snow or with ice? The lighter areas in the second piece are probably caused because the rubber bands were wrapped more tightly there. In both fabrics, the brown dye powder separated nicely in the component colors.
