Our mountains are lighter than air.

Saskatchewan is flat. If you wanted a simile for extreme flatness, Saskatchewan would be very near the top of the list.
It's also pretty devoid of any significant scenery other than sky. Consequently that's where I find myself looking most of the time, up up up.
I remember when I returned after spending 10 years in the mountains of Alberta and the West Coast of B.C. that I had the sensation of being at a tremendous altitude for my first few weeks back.
The absence of mountains on the horizon somehow convinced my senses that I must be high above the mountains. It was like vertigo those first few weeks.
I was riding in a friend's car at that time, and I spotted a line of storm clouds moving in far away to the west. I'd been looking at them for a few minutes before I realized that it wasn't a mountain range, but clouds, and I laughed to myself.
Yesterday I was out riding my bike on the edge of town and I saw a distant range of clouds rising over the horizon, and I was reminded again of the mountains, and for a moment I missed them. Only for a moment though. Soon I was full of appreciation for our mountains, lighter than air, advancing and retreating across the sky. You can watch a storm cloud boil and grow, and it looks like a great volcanic lava flow growing and rising. Our mountains light up with fireworks all summer long, and they turn and drop and can be 1000 different colors at once when the sun is setting. By far the very best thing about our moving mountain ranges of cloud, is that they are never the same as they were the day before.
Scenery is entirely dependent on focus.
