From late June through August, the Flatirons and the trails climbing into the foothills behind them are exposed to a near-daily cycle of building storms and lightning, and the difference between a great hike and a genuinely dangerous one is almost entirely a matter of timing. Get high early and you have the mountain to yourself in clean morning air; linger past midday and you can find yourself the tallest thing on an open rock face as a cell builds overhead.</p>
