I spent most of the 2002 field season on Bob Harmon's crew at Mark's Trike, a partial Triceratops skeleton. Plenty of frill sections and a lot of ribs, plus a few vertebrae. Every day we rode the boat across the lake and enjoyed a nearly 2 mile uphill hike to get to the quarry. On the way we would pass the old G-rex quarry, where a crew had satellite camped the year before. But no, we hiked. And in the evening, when the walk was downhill, we were beset by the most viscious biting flies I've ever encountered. Bug spray was a condiment for them.

We spent a couple of days taking the even longer boat ride and still longer hike out to help the B-rex crew with their massive cliff of overburden. They spent nearly the entire summer jackhammering that cliff. During the hottest part of the summer, they would wake up at 4 am and dig by moonlight to avoid the heat of the day. Very impressive dedication.

One day we hiked out to briefly visit the B-rex site, then hiked to the next coulee over to revisit X-rex. A small theropod bone had been found under X-rex's tail the previous year, so we went there in 120 degree heat to look for a juvenile tyrannosaur. We found nothing but heat sickness.

We also worked on various smaller sites, including Too Big, a site with several large frill pieces in an incredibly hard mudstone.
