Bird Island shows it's dangerous underwater Travertine spine that has caught
many an unsuspecting boater unawares.
Utah Lake water levels are starting to come back up.
These stunning aerial photos are the handiwork of pilot Dan Nelson.
Thank you Dan for these telling shots.
Bird Island is now visible from the Provo Marina.
How to compute "Line of Sight Distances"
To compute the greatest distance at which an observer can see the top of an object above the horizon, compute the distance to the horizon for a hypothetical observer on top of that object, and add it to the real observer's distance to the horizon. For example, for an observer with a height of 1.70 m standing on the ground, the horizon is 4.65 km away. For a tower with a height of 100 m, the horizon distance is 35.7 km. Thus an observer on a beach can see the top of the tower as long as it is not more than 40.35 km away. Conversely, if an observer on a boat (h = 1.7 m) can just see the tops of trees on a nearby shore (h = 10 m), the trees are probably about 16 km away.
Referring to the figure at the right, the top of the lighthouse will be visible to a lookout in a crow's nest at the top of a mast of the boat if
where DBL is in kilometers and hB and hL are in meters.

One spot still left for upcoming Catalina Island trip.
This is a great opportunity for a spontaneous 3 day escape.

Bonneville's Cape Dory Back on the Hard
Only 165 more days 'til she goes back in the water. Pressure washer does a great job of removing lake growth.
Still plenty of good sailing on the Catalina 25 that is still in the water!
We need a "filming boat" for a Utah Valley Convention and Visitors Bureau produced film about sailing on Utah Lake. Would you and your boat be willing to go out on the lake tomorrow the 15th at 4 PM with their film crew. Give us a call if this sounds like fun to you.
