The Lamplugh Glacier is a 16 km long glacier in the US state of Alaska .
geography
It is located in Glacier Bay National Park in the Panhandle of Alaska. The mean 1.5 km wide glacier flows from Brady Icefield , located in the southern Fairweather Range , in a north-northwest direction and flows into Johns Hopkins Inlet , a western side bay of Glacier Bay .
Glacier development
The lower end of the glacier is 1.2 km wide. The ice front protrudes on average 45 m above and 3–12 m below the waterline (status 2004). The ice speed was estimated at 300 m per year at the time. The retreat rate in the central and eastern part of the ice front was 15–30 m per year in the early 2000s. The western part of the ice front was already mostly dry at the time.
Naming
The Lamplugh Glacier was named by Lawrence Martin of the USGS around 1912 after the British geologist and geographer George William Lamplugh .
