According to the World Reviewer the San Rafael Falls are:
This is the largest and most spectacular waterfall in Ecuador. The San Rafael Falls are over 500 feet high and carry a huge volume of water in an astonishing display of nature’s power. They are located at the foot of the highly active Reventador Volcano which rises out of the Amazon jungle east of the Andes.
They are indeed quite impressive and worth a visit. This shot was taken with my Lumix LX3 in natural film mode and the 16:9 format. I took 2 shots horizontally and merged them into this one big image with Photoshop plus some minor adjustments in saturisation and levels.
