The picture shows how the "Fossil" material looks after the stone is ready to season. If you wait too long to remove the leaves, ferns, etc. They come out in small pieces and are a lot of work to remove. If you take them out too soon the impression will not be as sharp. I poured a stone at night and woke up early to remove the goodies only to find I should have removed them earlier, and ended up picking out the pieces and using a slow stream of water to soften the materials and wash away some of the excess concrete. I found some dog tracks in some of the stones, must have been an ice age coyote, going to the stream for a drink.
