No, book, no!
I have nearly finished reading In Search of Ancient New Zealand, a pop-science type geological history by Hamish Campbell and Gerard Hutching. It's easy enough to read that I've put up with the poor prose, and the fact it really could have done with another proofread. But. Talking about the Last Glacial Maximum as it occured in New Zealand:

Glaciers would have certainly formed on the major North Island volcanic cones of Ruapehu, Tongariro and Taranaki, but subsequent climatic warming and volcanic eruptions have erased the geological memory of any glaciers. There is no evidence.

And now I can't trust anything this book says. Indeed, I threw a hissy fit at it. Because not only are there still glaciers on Ruapehu (albeit very small ones), but there is certainly evidence of glaciers. I was looking at it last weekend! But now I know what fools we were, thinking those were lateral moraines we were climbing up. I'm sure my glaciologist lecturer will be very disappointed when I tell him. I may as well not do my mapping project, being as we clearly imagined the whole thing.

What the hell, book? Really, if I'd been further than 10 pages from the end of the damn thing, I'd be throwing it away in disgust.
