My original career goal was that of naturalist, or at least what I thought of as a naturalist. Visions of trekking around the world in search and investigation of rare and interesting animals somehow changed to realities radically different and much less “outdoors” but I never lost an interest in being a part of the naturalist world. Then, in the early 1990’s, I learned of an organization that could make part of this dream come true.
Earthwatch Institute at the time provided volunteers to work with researchers around the world, giving individuals the opportunity to be a part of on-the-ground research in a variety of fields. They were connecting people with projects all over the place, spanning a range that included biology, archeology, anthropology, sociology, history, geology, etc. and on almost every continent. You could just about find a place and subject to fulfill any dream your inner scientist might have. I’ve recently checked their offerings and it feels like they’ve pulled back a bit in the number of expeditions and the range of projects, but it is still a great way to connect with ongoing work in a variety of fields.
For my first expedition I wanted to go somewhere and work in cold and snow. Although we’d lived in a couple of places where winter was a real season I’d never spent time much further than the local woods so the chance to get out and do some real backwoods winter trekking was very appealing. And there, in the catalog, was the perfect expedition – tracking mountain lions in Idaho. In the winter. I sent in my application and check and started building up a wardrobe suitable to the adventure.

Southeast Idaho ridges and plains
The principle investigator for the project had been researching the impact of habitat loss on mountain lion populations, attempting to define how small a habitat could become before the big cats would abandon it. In that part of southeastern Idaho much of the geology is ranges of mountain ridges separated by plains, which over the years have become valuable farm land. Mountain lions stake out a territory through which they hunt and raise their young, and they are very reluctant to cross open area where man has extended his reach. As a result, islands of habitat were forming in the ridges and the objective of the research was to determine the minimum size required to support a population.

Farming in the mountains
The activity in the project was pretty simple: radio collar mountain lions and then track their movements to learn their habitat range and whether they left an area permanently. Simple in design, much more interesting in implementation. There were two teams annually. The summer team set up a base camp high on a ridge and used directional locators to track collared cats, gathering the significant amount of data to be used in the study. In winter, the other team could track the cats, capture them, take measurements and place radio collars. That was the part I wanted to be involved in – snow, winter, big cats.
That winter Idaho saw its driest season ever on record.
Whole mountain ranges were bare of snow and the lower plateaus and prairies were completely void of snow. OK, I thought, so maybe the playing-in-snow part wasn’t that important after all. Except, the devised way to track the cats was to find their kills in the woods and follow their tracks in the snow until we could get close enough to use dogs to tree them. No snow, no tracks.
Fortunately for the volunteers, the principle scientist had other assignments we could work on. Several cats had collars with batteries threatening to run out, which would leave the subsequent summer team with no way to collect data. It also meant we could use the radio tracking equipment to find the cats needing battery replacement (each cat’s collar had a unique signal so the researchers knew which animals to look for) and then follow the same procedure the research protocol gave for collaring.

Turns out mountain lions are very hard to find, even when you have a beacon leading you to them. Not only are they well camouflaged in the mountains but they are really very shy and stealthy. Our success rate was not 100% although we did capture and re-collar 12 adults and 3 kittens. I sat on the side of a valley one day and watched two parties triangulate on a cat that was on the opposite side of the valley, listening on the radio as the two parties converged only to find the cat had vanished. In plain sight. Very challenging.

Uphill, yet again
But the successes far exceeded the failures in excitement. Once a cat was found the dogs put it up a tree (which was probably a mile or so away and usually uphill and sometimes through knee deep snow so I got my fill of that), a tranquilizer dart was fired into it and a brave graduate student climbed the tree to attached a rope to lower the cat carefully down. On the ground the cat was weighed, measured for length, paw size, claw length and canine length, a blood sample taken, the ear tattoo checked for legibility and re-tattooed where needed, and the collar replaced. With all that done we all got chances to take pictures and examine the cats more closely. I found by putting my head against a big male’s chest that they purr just like a house cat, although at a much lower frequency!

All this work took about half an hour then the researcher injected a stimulate and we all backed away many yards to watch the cat recover and stagger back into the woods. After much congratulatory backslapping it was on to the next target.

The kittens were equally challenging since they were sometimes in trees and sometimes in the rocks. Being much smaller they were certainly more manageable and definitely more cuddly. Fortunate for us no mother cats came to investigate but we did always have one person on lookout for a brown blur heading our way.

All in all a true life experience, especially for my inner naturalist. And a unique opportunity for a photographer-to-be. I carried a Canon One-Shot film camera in a belt holster where it was easily accessed to make as many pictures as I could. All the images were made on slide film and I scanned them for some digital post-processing. Looking on them now I realize how documentary they are – even the landscapes are pretty static – but for the experience they suit my needs. Even now, 20 years later, I can glance at one and pretty much remember what was going on when it was made and recall the thrills of being a part of work that took me to such a wonderful place and meet these remarkable animals.
