Problem #1 Comments
While spatially variable, it was most certainly present. In areas where the snow had drifted in even a little bit and the snow pack was a touch deeper it was becoming more stubborn to get positive test results. Where shallow, moderate. I am leaving trend as same because it is a very, very small trend towards improving.
