Excerpt from 'The Echoes of Echo Canyon' Nora stood at the lip of the red-rock amphitheater, watching the shadow of a hawk glide across the sandstone cliffs. Her younger brother, Toby, tugged on her canvas sleeve. 'Are you sure Grandfather's old map is right, Nora? We've been hiking since dawn, and all I see are rocks and scrub oak.' Nora unfolded the faded paper, tracing the ink line drawn fifty years ago. 'Grandfather didn't mark this trail for convenience, Toby. He marked it because the ancient granaries are hidden in the alcoves where flash floods can't reach them. You have to look past the obvious dry riverbed to see where the real shelter lies.' Toby wiped sweat from his forehead, looking up at the towering cliffs with newfound focus. 'So the canyon isn't empty—it's just keeping secrets.' Nora smiled, taking a step onto the narrow ridge. 'Exactly. And we just need to learn how to read its clues.' How does Toby's character change from the beginning of the passage to the end?

Informational Article: 'Harnessing the Sun in the Great Basin' The Great Basin region of Utah receives over 300 sunny days each year, making it one of the most promising locations for solar energy development in the Intermountain West. In recent years, public utility companies and private enterprises have collaborated to build utility-scale photovoltaic solar farms across rural counties. These facilities capture solar radiation and convert it into clean electricity for thousands of homes. However, expanding solar infrastructure requires balancing land use priorities. Conservationists emphasize that large solar installations must avoid sensitive desert tortoise habitats and fragile sagebrush ecosystems. By utilizing degraded agricultural parcels and brownfields rather than pristine wilderness, energy developers are finding innovative ways to power communities while preserving Utah's unique natural heritage.
