What a lovely area!! I would get a long-handled shovel and start turning that soil over. Getting some of that good mulch down into the soil will help it. Is there a faucet near by? Buy a hose and add some moisture to the dry soil as well. Preparing the soil will help whatever you decide to plant later on. I am specifically talking about the bed beneath the raised bed. The raised bed seems to have a good start on an assortment of plants.
