A still sunrise

To demonstrate what I mean by shifting of the position of the sun on the horizon that I described in the previous post, here are two sunrise pictures from separate times of year at Palo Verde.  On the left is a photo I took in January and on the right is a photo I took this morning.  I know it’s not a new discovery to science, but I thought it was still cool to see, particularly because my previous experience steered me wrong in predicting the sun’s location; I had neglected to factor in the change in the earth’s tilt relative to the sun from January to May, which results in a sunrise that is further to the north.  Science is cool.sunrise-at-palo-verde-05042009-055653palo-verde-sun-rise-atop-a-mountain-2007-01-06-5-33-18-am-2007-01-06-6-09-25-am

For those of you didn’t explicitly appreciate the start of today

… I bring you the sunrise… well, without the sun.  In my second attempt to create a time lapse movie, I was unable to predict the location of the sun this morning.  When Adam, a graduate student who’s currently staying here for an OTS course, asked where we should point our cameras to get a good shot of the rising sun, I assumed that it would rise in roughly the same position on the horizon that it had in January of 2008 and 2007; over the mountains show in this video.  Nevertheless, the sun rises in a vastly different position now, in May.  Thus, neither Adam nor I took time lapses that included the sun in the frame.  Live and learn.

There was some fantastic fog though.

My shoes smell

At the dried lagoon, there are hundreds of thousands of dead fish, although I’m not sure of the species (or family for that matter).  I do have some living ones, so I’ll key them out as soon as I can.  The stench is terrible; further, it’s still in my shoes.dead-fish-at-laguna-bocana-05022009-113022dead-fish-at-laguna-bocana-05022009-113029

Where is Bocana

Bocana is roughly a two hour hike from the Palo Verde OTS field station where I am staying.  Below are some screen shots from Google Earth of the dried lagoon my previous post was about and it’s relative position to PVpvtobocana.bocana The little blue line is 0.5 km.



I found the Laguna Bocana, or lack there of.  There is an astonishing cliff face at and lots of vultures, but no water.  I did manage to find some living, rooted Neptunia (a plant I’d like to study), but it’s abundance appears to be very low for somewhat obvious reasons.   Eichhornia is also present, and thriving much better since it is relatively drought tolerant and the cows don’t appear to make it to Bocana as often.  me-at-laguna-bocana-05022009-122030
