"The white triangle that my model is inside — represents Aquarius."

On February 12, Leslie Monroy went out to the north side of Crystal Pier in Pacific Beach with a stick and a rake — to create art.

“The closest name that I can come up with is a ‘sand mandala’, but it’s not really a mandala,” she said. “I’m not sure what it is called, yet.”

“Regular dry sand is soft and fluffy and you wouldn’t be able to see the details.”

Monroy, an artist from Spring Valley, was referring to the 150-foot art piece that she carved into the beach during low tide.

“I did this design for myself,” she said, “[because] my birthday is on February 14. The white triangle that my model Jamie Shadowlight is inside — represents Aquarius. I used the white to show a clean slate as I enter my 33rd year.”

Monroy usually creates black and white pen-and-ink art and line drawings that are mounted on easels or displayed in galleries. She’s recently added these massive sand drawings to her portfolio, which is created on the beach when the tide drops, but when the tide rises back up: her “masterpieces” wash out to sea.

“I’m trying to do them once a month,” she said, “and I always do them here, north of the pier.”

Monroy used to surf PB until she sustained a gnarly knee injury two years ago, then in March of last year, she re-diverted that beach-vibe to create her inaugural gigantic sand drawing. Her birthday piece on Tuesday was her seventh one.

Monroy re-diverted her beach-vibe.

In December, she created an Aries-and-Mars inspired piece. “Aries is a ram,” she explained. “The triangle represents his head with two red eyes and the horns coming off of it; the symbol for Mars is the arrow.” She used about “370 apples” in the piece which were then washed and donated to a downtown homeless shelter.

One admirer saw drone photos of Monroy’s pieces and commented: “Dope AF (as f*ck)”; another said: “These resemble those UFO circles in the fields.”

“I used to draw lots of crop circles,” Monroy said, “so ‘yes’ they do have an influence. I don’t really have a set plan when I do this and I’m never really sure what it will look like.”

Monroy said that seven drone pilots offered to film her rake, carve, and assemble the Aquarius piece; another 20-or-so observed.

“I’m always down for people to watch, but probably not the first hours that I’m there."

“I’m always down for people to watch,” she said, “but probably not the first hours that I’m there, so I can get most of it done and get a good base down before people start talking to me. I really don’t want to be rude, but I have to fight the tide and only have a certain amount of time (2.5-3 hours).”

Monroy can only do this type of art when the tides out with fresh and wet sand. “Regular dry sand is soft and fluffy and you wouldn’t be able to see the details,” she said. “Mother nature rules on her canvas and I gotta do what she likes.”
