The Buttertubs Pass is a high road in the Yorkshire Dales, England. The road winds its way north from Simonstone near Hawes towards Thwaite and Muker past 20-metre-deep limestone potholes called the Buttertubs. It is said that the name of the potholes came from the times when farmers would rest there on their way to market. During hot weather they would lower the butter they had produced into the potholes to keep it cool.
