It's great if you're a duck

The end of week one of the project. I thought I got off to a good start given my limited time during the work week. The rain of Friday left quite a mess and I'm not sure it's a good idea to lay the base and stone in this condition. My biggest fear is that the walls will collapse if any weight is placed on them. Any one have a thought on this?

Late afternoon it started raining again and has only stopped briefly over the past two hours. I guess tomorrow will be a day of moving materials from the front of the house to the back. It's got to be done sometime. But what a mess the rain is making. I hope it doesn't ruin my work. Check out the pictures. This project may become a pond instead of a garden path.
