Answer:
The sand from the Huntington Beach area of California seems to be soft and white due to a mixture of small rounded Quartz particles mixed with even smaller powdery Carbonate minerals (probably from the shells of the diatoms in the surrounding waters). The Quartz crystals are very hard and have no or very few sharp edges. The Carbonates are mostly Calcium and very soft. They tend to grind down into a powder between the Quartz crystals. The sand would be easily removed from the beach by ocean water if not for the 30 inch high concrete walls which have be built to prevent the movement of the sand.

I grew up in Huntington Beach and I didn't know that that was the best sand in California.That's nice to know. Well over all Huntington Beach is a very very nice city and downtown HB is very nice especially at night.

One of the main things that makes sand feel 'soft' is the size of the individual particles. Take a handful of rocks and then a handful of sand. The sand will undoubtedly feel 'softer' than the rocks. It's the same thing with different qualities of sand. The average size of a grain of sand is between 2 to 0.06 mm. If they get smaller than that, it's usually referred to as 'silt' instead. And one of the ways to tell silt from sand (other than by measuring grains) is - you guessed it - to rub it between your fingers and see how it feels. Sand feels grainy while silt feels floury. The only reason why one beach might have one grain size and another beach a different one is currents. Small grains are more easily caught up and moved by water flows - many rivers show patterns of picking up sand in fast-moving (and rocky) parts and leaving them at slow-moving (and sandy) curving parts. The ocean does the same thing. So if Hunington Beach has particularly fine sand, it might just be at a place where ocean currents slow down a bit... it would not only not lose its small-grain sand but pick up more sand from elsewhere!
