Newbie question

I am creating hugelbeds on a slight slope which faces south. Am I correct in that I orient my beds across the face of the slope ( east/west) rather than up and down the length of the hill? I would definitely appreciate feedback, as I will be digging in multiple beds ( yay for a tractor w/ backhoe!) and want them done correctly!

Aligning them across the face of the hill, the way the contour lines run, helps with water retention. Have fun with the backhoe!

Thanks so much, John! It seemed logical to me.......and since I will be digging to sink my logs and branches I really wanted to make sure I was thinking correctly!
