Back in 1974, when I was in my early twenties, I befriended a group of hikers who were mapping a desert trail from the Mexican to the Canadian border. Offering to try a few routes for them through Death Valley, I made the drive to a base camp near Ulida Flat, where I camped for the night.

At first light, I started my trek¹ up an alluvial² fan into an unnamed canyon³ in the Cottonwood Mountains. After about an hour of hiking through the rock-strewn

wash, I made my way deeper into the shadows and the bray⁴ of a burro told me I wasn't alone. With slow, careful steps, I rounded a bend and found myself in Burroville - Population: 100. I looked around and saw that the majority stood in little groups along the slopes while several others were perched atop the perpendicular⁵ cliff walls.

I continued walking and was soon met by an imposing⁶ welcoming committee-a dozen big Jacks⁸ with massive heads, standing⁹ shoulder to shoulder and daring me to approach. Though they stood a good thirty feet away, their resolute¹⁰ stance and effective blockade of the canyon ahead made me pause a while to consider my next move. I'd never heard of anyone being killed by a burro, but it was clear they had no plans to let me pass.

Several moments went by until one of the big Jacks pawed at the ground with his hooves and another looked behind him, as if to check the rear for a surprise attack. That's when I saw what the burro was actually looking at - a Jenny and nursing foal standing close beside the canyon wall about twenty feet back. Our eyes met and the female's flanks shuddered¹¹ as she watched me with a wariness¹³ that only a true wild thing can display.

When I lifted my gaze to scan the slopes behind her, I was surprised to see other females and their young, planted in groups of two and three all around me. Suddenly I realized it was the time of year for foals to drop, and the big males were merely protecting their mates and babies. I must have let out a big sigh, because one of them pricked¹⁴ up his ears and raised his head as if waiting for me to speak.

"Don't worry, guys, I'm just passing through," I called gently.

No response, just a flutter of flanks and a few ear twitches¹⁵. Clearly, the subtle approach wasn't working, so I picked up a rock and lobbed it near the biggest Jack⁷. It fell at his feet and he lowered his head to sniff¹⁶ it.

Clearly the burro had no intention of moving, so I reluctantly turned and began to make my way back down the wash in defeat. That was when a loud bray made me about-face once more.

To my surprise, the big jacks were lumbering¹⁷ out of the wash and making their way toward the northern walls of the canyon. Now, only the biggest of them remained at the edge of the bank, staring at me. Suddenly, the way was clear; I'd won the standoff. I started up the canyon but was stopped by the look in the burro's great brown eyes. As we stood there staring at each other, a shudder¹² passed through me.

In that instant the message he sent me became clear: he was asking me to leave the canyon. Politely, and with some measure of supplication¹⁸, but plain as day. And I knew then I couldn't go on, couldn't violate his trust. So I turned and headed back down the canyon.

As I retreated, I considered my role in creating a desert trail that hundreds of hikers would traverse each year. Today's unknown route through a rugged¹⁹ canyon might well become a dotted red line on some future map. Was it so important that people knew about this place? I began to think it wasn't.

Maybe what this earth really needed was a few more unnamed canyons²⁰. Maybe there's some intrinsic value in knowing that some mountains will never be climbed, that a handful of jungles will remain unexplored. Must we really clamber up every alluvial fan, map every desert canyon, and slap a name on every dry lake and rocky outcropping?

Perhaps, in the end, it's enough just knowing they're out there -somewhere.
