I taxied into ANC lately. The ramp had so much snow, it was all white. No taxiway markings, no lights, no nothing, just a lot of white. Ahead of us a good ways we could see some markings, which helped us stay on the center of the taxiway. We just had to go straight a ways, and then were turned in with marshaller help. If we had to make any turns, going a longer distance, guess we would have needed a tug. Not sure how bad the ORD ramp was at this time...could have been a factor...
