the colouring is quite effective.
Shale is pretty interesting (oh god, did I just say that?) in this region. It's referred to as "Marcellus Shale" and stretches from NY state, through Pa, and into Ohio. It has layers of black shale, limestone, and shale containing iron (how the hell else did Bethlehem and Pittsburgh get their claim to fame?) which has a nice rich rust color.And with my pride bruised, I tore down the other faces I carved, since I am way more satisfied with the outcome of my latest efforts. Yeah, you win Robert and Peteski.
