Ken Amor's recognition that the Stac Fada Member is an impact deposit (Amor et al. 2008) proved a game-changer. I planned only to collect a piece on a holiday visit in 2011 but have since walked the entire outcrop and examined every exposure on multiple occasions. My observations extend far beyond what was outlined in my original paper (Simms 2015) and I recognize errors in the latest contribution by Amor et al. (2019).
