- Field trip to the Wells Creek volcanics, North Fork Nooksack River (nwgeology.wordpress.com)
The Wells Creek Volcanic Member of the Nooksack Formation (Tabor and others, 2003; see refs below) is found in the vicinity of Nooksack Falls, east of Glacier, Washington.

Anyone who has done any graphical programming also knows that visual rendering relies not just on pi but trigonometry more broadly as well as other mathematical techniques. If we look into the source code of the first person shooter Doom we find that the value of pi used in the game is wrong. In this talk I will explore what happens when we subtly and not so subtly break math in the source.

Wells Creek is a swift creek in Whatcom County, Washington. It is a tributary of the Nooksack River, joining the river just below Nooksack Falls. It is best known for having six major waterfalls along its course. Wells Creek was named for Hamilton C. Wells who prospected the area in the 1880s and 1890s.
