At the site of
Well 40 (Natawalu) there is a large lake subject to flooding. A track leads up to the top of a
hill behind the
Well site to the grave of Michael Tobin. Michael was speared in 1907 during the main survey of the stock route. His grave has a marble cross and clear embossed lettering with all the details of his death. A fence around the grave was rebuilt in 1987.
Well 40 is also known as Waddawalla.
