Over the past 25 years, I’ve written and/or illustrated several books, on subjects ranging from underwater insects to Alaska’s glaciers. I’ve written for all ages, but my current focus is children’s natural history picture books. As an author, I’m represented by Mary Cummings, of Great River Literary.

I love doing school author visits, readings and book-related lessons. Let me know if you’re interested in scheduling something. And I want these books to be the best resources they can be for teachers, parents, caregivers, and kids… so I’ll be happy to talk about lesson plans that help enhance their content. Contact me to discuss the possibilities.


Candlewick Press is going to publish my new children’s picture book! I Was is a science book… and it’s narrated by skulls. As six different animal skulls tell their stories, children learn how the features of each skull tell about that animal’s life. The book will be illustrated by Natasha Donovan.

It won’t be out for a while, but I’m familiar with how long it takes to illustrate a book, so I’ll just enjoy the process and the anticipation!

Years of watching humpback whales on the water near our home led my co-author, Cheryl Cook, and me to write this children’s picture book. Available here.

This children’s book grew out of a multi-year research project studying the ecology and behavior of American Dippers. It was self-published at first, then picked up for publication by Yosemite Conservancy. Available here.

Ecologist Mary Willson and I wrote this book about our favorite research subjects. Out of print.

A tour of the dazzling diversity of aquatic insects in Alaska! Available as a free PDF from Bob Armstrong’s wonderful website – (and while you are there, make sure you take a look at all of the other books, photos, and videos that Bob has generously made available).

This middle-grade science book, published by Alaska Geographic, won a National Association for Interpretation Small Books Award in 2007. Available here.

I grew up within sight of the Mendenhall Glacier, so when I was asked to write this book for Alaska Geographic, I jumped at the chance! (Out of print)

For several years I was a teaching naturalist for the Juneau-based nature education nonprofit Discovery Southeast. In collaboration with naturalists Richard Carstensen, Steve Merli, Terry Schwarz, and others, I helped write, design, and illustrate several books and field guides. Several of them are still in print, and available here.

This “food chain tale” was published in 2000. It was a small, self-published project but it did end up helping quite a few primary-school educators teach about ocean food chains. (Out of print).
