I'm wondering if anyone can clarify this? OS map and F&R guidebooks both go for Wallowbarrow, while the farm which provides the car park calls itself Wallabarrow (disagreeing with OS map). UKC search doesn't recognise Wallabarrow. Personally, I have a preference for Walla, as it sounds more Cumbrian somehow, and trips off the tongue better. There is also a Walla Crag in Borrowdale, and I suspect the word has some descriptive meaning in Cumbrian dialect, but a brief internet search didn't reveal anything.
