Summary:
Specific type section is changed to moraine in center of West Fork valley 1 km southwest of Garda Falls and 2.5 km northwest of summit of Burroughs Mountain, Pierce Co, WA. Pyroclastic layer C directly overlies till on this moraine, and layer Y is absent. Layer Y was found at base of two uprooted trees on moraine selected for type section by Crandell and Miller (1964); this moraine is evidently older than Burroughs Mountain Drift.
