I don't know how to feel about Mt. Catherine, I understand it's the highest mountain in Egypt, but I had never even heard of it and it is right next to Mt. Sinai. I thought I was going mad typing Sinai again and again!
Great quiz. Only missed the mountain in Iran. By the way, (M(OUN)?T)?SIN+A[IY] would be a good type-ins addition, as nothing related to Sinai was accepted. I only got the right type-ins (Catherine) thanks to comments.
