they flow from their glacial sources in that it has a more basin-like expansion in its lower half. This basin-like expanse, which is about 2 miles (3.2 km) wide along the trail and gradually narrows into a mountain gorge valley 0.5 miles (0.80 km) wide toward the head of the river as the glaciers are approached, is floored with deposits of gravel, sand, and mud. In an ascent of Lakina River from the main trail, the first bed rock to present itself along the margins of the flat gravel floor of the valley is the
Nikolai greenstone. This rock appears on both sides of the valley where the valley begins to become more restricted, about 3 miles (4.8 km) below the glaciers, and rises in steep mountain slopes on both sides. Above the greenstone, the Chitistone limestone presents its characteristic cliff-like faces, and above the Chitistone limestone, a series of shales and thin-bedded limestones on the east side of the valley forms bare slopes that are also present, though not so evident, on the heights west of the river.
