Time Machine – A Request

Hi I have recently stumbled upon a postcard a yard sale from 1942 Sept 9th. The post card was sent from J.E. Delaville (R.118015) to N. Ward (R.103830 stationed at No.7 SFTS at Macleod Alta. sent to Cpl N. Ward station at RCAF Yarmouth Nova Scotia.

The post card is a picture of Cameron Falls at Waterton PK Alberta. If you have any info of either of these two for there ancestors I would greatly appreciate it.

It’s very intriguing! Thanks
