CEDO.. A place for fun and to learn

CEDO Logo Rocky Point

Have you ever driven through Las Conchas here in Puerto Peñasco Mexico  and about half way through noticed a huge Fin Whale Skelton on a hill side?  Well welcome to CEDO, the  Intercutural Center for the Study of Deserts and Oceans.  CEDO is now over 35 years old and growing.  It was started as a non profit collaboration between the University of Arizona Tucson Ecology and Evolutionary Department and the University of Sonora in Hermosillo.  It was designed for research, education and adventure and it is the place to learn about where the desert t meets the Sea of Cortez eco system.

Rocky Point Bird Island

It offers Tide Pool walks, Kayak tours in the Estuary Morua, boat trips to Bird Island as well as El Pinacate Biosphere reserve tours.  One of the next big events will be the “Wet Feet Camp” for children July 2 – 6.  Please check the CEDO calendar to sign up.  CEDO also has adult programs as well.

In 2007 CEDO won Mexico’s National Conservation of Nature award for their 27 years of effort to protect the Gulf Of California as it is also referred to.  It has been instrumental in the “Saving the Vaquita” an endangered specie that now numbers way below 50. They have also been instrumental in helping the Sea Turtle survive when they come here to lay their eggs and to make certain they are not disturbed.  CEDO has many educational programs and exhibits and promotes sustainable and conservation use of our natural resources.  One of its goals is to  create thriving coastal communities that are self sustainable while maintaining a healthy eco system.  They have also have been instrumental in saving the Totoaba an endangered fish.

This brings me back to the Fin Whale.  The Fin Whale is one of a couple that visit the Puerto Peñasco area.  They generally arrive in February and hang around for a few days.  The past few years they have arrived in January and have stayed for up to a month.  They seem to like the view as much as the residents do!  You can go out on Whale watching tours during those times and do remember to bring your camera.  Many times they can be seen just a few hundred yards off shore from the Sandy Beach resorts.  The Fin Whale at CEDO is about 55′ and was a youngster when it met its demise.  Adult Fins can grow up to 75′ long.  Sadly we have had over the time I have been coming here, seeing them washed up on shore south of town.  While in Cabo San Lucas years ago I asked our fishing captain why do we have them wash up beside the extreme high Tide changes that Rocky Point has?  His explanation was simply that if a Whale gets sick on it’s journey from Alaska, they think that if they get into warmer waters that they will get better!  Makes sense as the are very smart mammals.  But unfortunately they don’t make it.  If you should ever come up one that has just arrived, please notify CEDO.  Do not remove any part of the animal and DO NOT try taking it or any Turtle pieces back across the border with you.

Take the time and visit CEDO and tour the “Earthship”.  In 1992 Jeanette Clifton visited Taos, New Mexico and learned about the construction of these buildings out of old tires and cans.  In the Taos area you will see them dotting the hillsides.  It started with 240 tires.  It features an 18′ dome made out of aluminum cans and a cement type mixture that is like Adobe.  It is self sustaining.  She devoted her tireless efforts to see this project evolve.  There are 2 sections to this complex as well as a place where students stay on field trips.

Cedo at Las Conchas

The “Earthship” houses the gift shop and store.  Here you will find many books about the area and probably one of the best book stores in Rocky Point as well as CEDO Tide Calendars, shirts and other apparel , “Save The Vaquita” shirts and earrings. It is here where you can also purchase the famous Mata Ortiz Pottery as well as items including indigenous crafts and art from Oaxaca,  Chiapas and Chihuahua.  There also baskets from Tarahumara and pottery.  If you want you can also purchase a hand painted tile to donate to the CEDO walls with your names or children or grand children’s names.

When is Whale Season in Rocky Point?

Believe it or not, Puerto Penasco is one of the best places you could go for whale watching. The Sea of Cortez seems to have something to offer most of the animals, or mammals that live in the ocean. After grey whales have filled up on massive amounts of krill that come to the surface in the Bering Sea, they migrate to the Sea of Cortez which offers an ideal temperature for these whales to give birth to their calves. During this time of year the whales will mate and give birth to their calves only to return north again and start the process from the beginning.

If you want to increase your chances of seeing a whale you want to come during “whale season.” The best time to come is between early February and mid-May. On occasion you maybe able to observe whale behavior, such as breaching or a whale shooting a spout of water 25ft in the air, from your condo balcony, but if you want to get the most out of your whale watching experience we recommend booking a whale watching excursion. These excursions don’t promise a whale siting, but they do know where to go looking for these whales and do significantly increase your chances of seeing one. Always have your camera ready because you never know when a whale is going to breach (jump out of the water) and you don’t want to miss this opportunity!

There are several different kinds of whales that come to Rocky Point such as fin whales, grey whales and you may see one you didn’t expect! For example, in March a group of fisherman unexpectedly had a killer whale surface behind their boat. They then realized there were 2 more killers whales, which were only inches from the boat! The captain and his crew said they counted and there was a total of 12 whales that were following the boat and playing in it’s wake until they lost interest and disappeared! Something interesting that you can notice from these pictures is that even though this 31ft fishing boat is traveling at full speed, the killer whales seem unaffected and are able to easily keep up with the boat. This is a testament to the true power that these whales posses and their ability to travel at very high speeds for long distances.

Rocky Point Marine Life

If you have ever been to Rocky Point before you know that when the tide goes up and down, there is a significant difference on how the beach changes and what is exposed. With the tide moving so drastically, there are certain marine life animals that have to learn to adapt and survive in such an environment.
The tides in Rocky Point can be split up into four different depth zones. The first zone is home to those species that can be exposed to the air consistently, such as buckshot barnacles, periwinkles, and impets. Zone 2 is where we tend to see several species of crab and also the turban snail. As the tide continues to go down, zone 3 is home to hermit crabs, sea anemone’s and several different kinds of starfish. When the tide is at its lowest point, zone 4 these sea creatures only see beyond the surface less than 9% of the day. Animals that reside in this zone are specis such as: sea urchins, octopus, and red abalone. There are several animals that can be found in the deeper parts of the Sea of Cortez where they don’t run the risk of being exposed to the sea air. You can find  animals such as stingrays, hidden beneath the sand all several different species of fish further out in the deeper parts of the ocean.
The Sea of Cortez has a very unique marine ecosystem because of the differences in depth among the ocean floor. You can find sharks who like to reside in the warmer parts of the Sea of Cortez, or you can be a deep sea fishermen who is off in the deep blue looking for sailfish or marlin. If you do happen to be far enough in the ocean you may have the experience of being followed by dolphins. Dolphins enjoy to swim along side boats and jump acrobatically in the air and if you’re lucky enough to may get to see a humpback whale soar through the air. In order to see humpback whales though you have to come at the right time of the year. If you do come at the right time, see if you can book a tour because the professionals know where to go in order to increase your chances of being a whale.

The Sea of Cortez, often referred to as the “Worlds Aquarium” is an extremely unique experience for any marine life lover. You will not be disappointed with a day out in the Sea of Cortez.
