As one of our most popular vacation spots, the San Juan Islands are best known for their beaches, trails, whale sightings, and breathtaking natural beauty. But if you’ve spent any time in Friday Harbor on San Juan Island, you may know that there’s a spooky secret spot that’s loaded with symbolism.

The McMillin Mausoleum, also known as Afterglow Vista, is the final resting place of the McMillin family.

Travis / Flickr John McMillin owned the local lime works and was active in local and state politics. When he was 81, he began construction on a mausoleum for his family.

John McMillin was a staunch Methodist and an active Mason, so he used quite a few symbols when designing Afterglow Vista.

Travis / Flickr He chalked a large part of his success up to his faith and his personal philosophies. By the time he passed away in November of 1936, the mausoleum was complete.

The mausoleum contains the remains of John and five of his family members.

The most striking feature is the large, limestone table on the platform, which symbolizes the family meeting together in unity.

Every night when the sun goes down, this place really does seem to glow… but some think there’s more to it than just the fading light.

Ken Lane / Flickr Some people swear they’ve seen the spirits of the family members gathering around the table for dinner.

One of the pillars is broken, but it’s no accident.

There are many more symbols here – nothing is an accident.

To reach Afterglow Vista, follow the trail through the local cemetery in Roche Harbor.

Did you know this cool and creepy mausoleum existed? It’s amazing what you can find in Washington when you look hard enough.
