One evening I climbed a high ridge that stood about half a mile in front of a heavily forested peninsula which the fire-front would reach in a few hours. The fire was advancing across the valley with a front of about two miles. On arriving at the top of the ridge, I came up behind a grizzly bear seated on his haunches like a dog, intently watching the fire below. On discovering me he took a second look before concentrating his mind on a speedy retreat. Along the ridge about a quarter of a mile distant, a number of mountain sheep could be seen through the falling ashes, with heads toward the fire, but whether they were excited or simply curious could not be determined.
The forested peninsula which extended from between two forested cañons had a number of meadow openings on the slopes closest to me. Around these were many brilliant fiery displays. Overheated trees in or across these openings often became enveloped in robes of invisible gas far in advance of the flames. This gas flashed and flared up before the tree blazed, and occasionally it convoyed the flames across openings one hundred feet or so above the earth. Heated isolated trees usually went with a gushing flash. At other places this flaming sometimes lasted several seconds, and, when seen through steamy curtains or clouds of smoke, appeared like geysers of red fire.
At times there were vast scrolls and whirling spirals of sparks above and around the torrential, upstreaming flames of the fire-front. Millions of these sparks were sometimes formed by high outflowing air streams into splendid and far-reaching milky ways. In moments of general calm the sky was deeply filled with myriads of excited sparks, which gradually quieted, then floated beautifully, peacefully up to vanish in the night.
