It appears that they landed in the meadow of SNOW VALLEY, to the north of ASH CANYON CREEK. The Sierras are in the back ground of "the proposal" with the typical Calif smog layer being seen. When Megan is showing her beautiful ring, MARLETTE LAKE is directly behind Megan, and what looks like a peninsula, is in fact, the ridge line between MARLETTE LAKE DAM and Lake Tahoe. A perfect place for a COVID free proposal.
What great memories for the both of them. May they have a lifelong and beautiful marriage.
