In a short time the riders reached another Park but this one was not half the size of the first. Instead of encircling forest trees, the girls saw giant up-thrusts of rock that deft the blue sky. On each side of the widened trail stood lodge-pole pine that ran up to the summit and down the other side of the peak.

"At last—Top Notch Trail!" exclaimed Polly.

"You seem relieved?" ventured Anne.

"I am, because I half-doubted whether I would remember the right route without an older guide."

"When in doubt don't do anything," suggested Eleanor.

"If we didn't do anything we wouldn't have been up here," argued Anne.

"This trail runs straight to Grizzly Slide, a glacial peak I've always wanted to see. Father never had time to take me and mother wouldn't allow me to find it alone. Explorers say it is a permanent glacier that seldom changes its form as most of our other snow-capped peaks do in summertime."

"How I'd love to see it!" sighed Eleanor.

"It sounds as if we were in Switzerland about to visit the Alps," added
Barbara.

"Have you any plans for to-day, Polly?" asked Anne.
