Narrative:

Taxiing out of north cargo we were given lima to bravo. There was snow on the ground obscuring the taxi lines and the airport info page 10-9 depicts lima as a large paved area connected to bravo; but when we taxied we saw some markers that we went around to the left and then onto bravo. When we pulled up the parking gates 10-9B page diagram we saw that there is an area between lima and the general aviation ramp that is not depicted on the 10-9 airport info page. I believe we stayed on the taxiway at all times but we weren't on lima. The 10-9 page needs to be updated to show that area.
