Fill an open canyon

I am trying to fill in a submarine canyon so that profiles across the continental slope are flat. The fill tool does not work because it is open on one end.  Does anyone have an idea of how to do this?

I've tried deleting data where the canyon is and then interpolating across, but the edges do not match well with the surrounding bathymetry.

Thank you!
