Looking for an Outline Transparent Image of Thetis Island

Happy New Year, Thetis Islanders, 

I am working on a project and am looking for an outline of Thetis Island map (PNG / transparent). An outline is ideal but would also be happy with one with contour lines. 

If you have one or know where to find one/make one, please email me at charlotte@thetisislandnatureconservancy.org

Best,
Charlotte
