Wyatt is an aspiring scientist who takes note of all relevant data - from elevation and temperature to longitude and latitude. More analytical and cautious in his decision-making, Wyatt often rejects Gannon's passionate plea to take action without first having a well thought out plan. This creates tension and humor with his "fly-by-the-seat-of-his-pants" brother. A believer in science above all things, Wyatt strongly discounts Gannon's superstitions and mythical beliefs. Despite his brave demeanor, Wyatt is very jumpy and terrified of spiders. An avid photographer, he always has a camera around his neck.
