Just north of San Francisco, the Richardson Bay Audubon Center & Sanctuary overlooks 900 acres of open water that is closed from October 1 to March 31 each year to serve as a sanctuary for migrating waterbirds. This beautiful property is maintained by the Center with trails and gardens that are open year round, summer camps, a youth conservation leadership program, and numerous volunteer opportunities.
As a metal detectorist, I’m interested in the history of the property which includes the Lyford House – a home originally located at Strawberry Point, moved by barge in December 1957 when threatened with demolition. Once owned by Benjamin Lyford (1841-1906) and Hilarita née Reed (1839-1908), it is now listed on the National Register of Historic Places.
After speaking with the Center Director and obtaining permission to metal detect on Lani’s Beach lining the property, I am now cataloging my finds and learning more about the history of the property and its owners.

Because this is not a tourist beach in the traditional sense, the items found on this property are more likely to be relics of another time or items washed up from Richardson Bay. Some items discovered so far include Winchester bullet shells dating from 1901-1920, what appears to be a shoe buckle, mystery pieces of metal, vintage lead fishing weights, pieces of a small statue, and more. I’m excited to see what turns up after I spend more time on the beach.

It would be no surprise that in the early 1900s this would be a good spot for hunting. So far I’ve found four of these shells on one small area of the beach along with some other smaller caliber shells as well.

I encourage locals to volunteer at the Richardson Bay location, or plan a visit! Let them know that GeekyBeach sent you.







A beachgoer in Miami Florida contacted me early morning on May 12, 2021 to recover a diamond ring lost the night before. She was a wreck searching for the ring and couldn’t sleep. Fortunately, she kept track of her position on the beach and we met before sunrise on Haulover Beach in Miami, Florida, USA.

I made my way to the beach and recreated their approximate location from photos they had taken while on the beach. We communicated during the process and I found my way right to the correct spot. Two other couples were on the beach relaxing, so I was sure to let them know why I was invading their space!



I always share that it would be best to leave them at home, but if you’re traveling it can be scary to not have them on you. So at the very least, engraving your precious items can mean if you lose them it’s easier to know that it belongs to you. Some people use things like this 

After cleaning it up, I was able to read the text on the inside of the plastic wheels which included “Gullane (Thomas) 2003” and a quick search shows that it is a very destroyed Thomas the Tank Engine toy!
We couldn’t manage to get a nice photo in the dark and unfortunately lost touch when they returned home, but they were so happy to have this ring back where it belongs. They are a little shy about appearing in a photo for me, so unfortunately I only have a blurry night photo.
