"..... For twenty years, 1883-1904, amid his missionary endeavours with the Babine, Carrier, Sikanni and Chilcotin peoples, Father Morice systematically explored north central British Columbia. Working with only a watch, a telemeter, a compass, a mountain barometer and a sounding line, he produced the first real map of the area, one of amazing accuracy and detail. For the tragi-comic story of how the civil servants in Victoria refused to accept the names which Father Morice had attached to his newly discovered rivers, lakes and mountains, see the introductory essay which opens this book [pp.8,9]."

"The traditional Wet'suwet'en name is Wet-zuhn-kwa (pronounced Wet-zin-kwah). This means the "blueish-green colour of the water." Morice Lake is called Wet-zuhn-buhn. In the Wet'suwet'en language "kwa" refers to river or stream, and "buhn" refers to a body of water like a lake." (information shared February 2005 by Gary R. George, as told by Rita A. George and the late Andrew George Sr., all Bulkley Valley residents of Wet'suwet'en ancestry.)
