HOW FAR CAN YOU SEE IN BAJA?
Yesterday from the development hills above the ranch (150ft according to the topo), I could see Isla Santa Margarita in Bahia Magdalena in the clear
winter air.
I checked on Google Earth, and the exact distance between my position on the hill and the tip of the island mountain is 63 miles . .. that seems
awfully far, yet the island mountain was clearly visible.
I Googled "how far can you see" and got all sorts of answers, the main one being on the ground the horizon is 3 miles away. The formula (WikiAnswers)
is
http://wiki.answers.com/Q/How_far_from_the_shore_can_you_see...
"From basic geometry, you get that the distance to the horizon is D=sqrt(2Rh) where D = distance to horizon R = radius of earth h = height of
observer, which would be the height of your eyes . . .. "
So at a height of 150 ft, one can presumably see
D=sqrt(2*20e6*150) = 14.67 miles . . . .
As a mathematician, I am a fair guitar player - can some guru tell me where I am going wrong?
To confuse totally, I remember clearly being able to see Malarrimo Beach from the top of the road to San Fransisco de la Sierra - and that was about
77 miles according to Baja Almanac.
I need a Ballena . ..

My first flying trip down I could see about 200 miles.
I was using the islands for navigation. It still took me over an hour to get to each one.
That was a very clear day!

You have the run the computation from both ends. Google Earth says the highest elevation on that island is about 1,500 ft. Running the formula, you
should be able to see about 47 miles from the peak. To that, add the 15 miles you can see from your elevation, and the total is about 62 miles.

A old saying was that a man sitting on a horse could see about 7 miles.
On a real clear morning at a elevation of about 470 feet, and about 5 miles West of the western shore of the Sea of Cortez, I can see the bluffs in
the area of El Golfo on the ease side of the sea. Also the Altar mountains which are farther inland. El Golfo is a little over 50 miles and the
mountains are around a hundred miles.

Sitting in a bar,
Wondering if they can really,
See that far.

When I hooked a yellowtail this trip I looked in the water and he looked small. But I could tell by how hard he pulled he was grande.
I guess I could see about 100+ feet down. I watched him fight the whole way up.
Amazing!

I particularly like to stop on the hills past El Rosario going south to Cataviña and just "See forever".

On any clear morning I can see at least one to three islands that are part of the Islas de Encantada chain that are between Puerocitis and Gonzaga
Bay. We are 25 miles north of Puertocitis so I am seeing islands that are at least 45 to 55 miles south and my home is at sea level.
By the way...Today in San Diego (Point Loma to be exact) there is a clear view of San Clemente Island and Catalina Island.
Haven't had a bad trip yet....

Arrowhead - you nailed it. I forgot the height of the island . . . it took me only 3 Ballenas to get the correct answer.

Watch this video and take a ride in a U2 at 70,000 ft and run the numbers on the distance you can see from there. I think Baja is down there
somewhere. Pretty awesome.

I thought I read once that the furthest one can possible see on the surface of the earth is about 90+ miles, assuming that both objects are relatively
the same elevation.
After that, the curvature of the earth makes objects disappear below the horizon.
But, as some have noted here, the curvature of a woman or a beer bottle can alter physical law.

Hook, wouldn't the true line of sight be at sea level which is 17 miles?
From Point Loma today we clearly saw San Clemente Island and that is 60 miles from where we stood. Ok, maybe 90 would be the limit but our elevation
was pretty high, seems I could have seen further if there was an object to look at and if also it was clear enough.
When we drove to sea level the top of the island was still visible but only because it is high in elevation.
Haven't had a bad trip yet....
