It was almost sunset by the time we clambered over some boulders at the top of a steep slope. Looking higher, we could see the imposing hulk of the mountain in the fading light. Its sheer granite slabs were turning a bright orange as the sun edged lower in the sky. Up here it was easier to grasp the height of its summit, vertically about half-a-mile above the desert plain below. From our campsite at the bottom it looked considerably lower. I recalled the story of the guy who'd attempted a parachute jump from up there - and got smashed against the cliff by a strong gust of wind. At least, we weren't about to try anything as risky. We'd reached the highest point of our climb and were now looking for a suitable spot where Marlene could pose. It would be our last "nude in nature" photos for the day, out in the middle of nowhere. The cold wind had subsided, so goose-flesh wasn't going to be as much of a problem as during our morning shoot. I remembered the surprise-guest we'd had then - with no clothes nearby, Marlene had just hunkered down and hoped her naked body would blend in with the surrounding rock... We weren't too worried about spectators up here, and hadn't actually seen anyone for hours. I was now focussed on capturing the stunning vistas behind Marlene before the sun dipped below the horizon. I didn't yet think about how we'd find our way back down in the darkness... What was more important now were Marlene's high-heeled boots: we hadn't brought them along for nothing. She got them on and, nude once again, took a few wobbly steps closer to the edge. As a breeze wafted over her skin and through her hair, I eyed the precipice that dropped away behind her. This twilight spectacle was both sexy and scary at the same time... OUTDOOR NUDES
