What is that blue wire? If it is the equipment ground then it must be inside the conduit with the other feeder conductors.

It has absolutely nothing to do with frost, or where you live, unless you are talking about running water underground.
It has to do with NEC table 300.5.
Any outside feeder or circuit conduit can be 18" deep. In a residence there is NO requirement for deeper, unless of course your local codes say so, and this would be very rare.
