The amount of water held in snow depends on a number of factors including the temperature, length of time on the ground, rainfall on the snow, etc. I collected some very "wet" snow and let it melt. The container is 10-inches tall, 4-inches wide and 4-inches deep. This is a 30 second time lapse video, it took the snow around 3-hours to melt.
The dark object in the melting snow is a seed that was inadvertently collected along with the snow.
