A Seward Peninsula Vista

Scenic view of the Seward Peninsula, Alaska. Photo taken from a ridge above Graphite Creek, looking northwest towards the Imruk Basin. This area of the Seward Peninsula holds the largest graphite deposit in the US known as the Graphite Creek Deposit. Graphite is a critical mineral which the US relies entirely on imports. The USGS has been studying the geology of graphite deposits to learn more about how they form and where they are likely to be found, to improve the future domestic supply chain.
