Floating Uros island

Lake Titikaka is known for its floating islands. The name means Puma and it actually looks like a Puma when taken a pic from space.  It is still a mystery given that the lake was name thousands of years ago when there was no tech to take pics from the space.  It would take a year to build an island and could last for 25 to 30 years. The guide said there is no facility for washrooms on the island and they have to take a boat to go to a special island  to use the toilets.  We were so shock to hear the statement. These people must have a strong bladder.
