Missing teen Mina Patel near Kaaterskill Falls

I lost my 16-year-old sister Mina Patel yesterday around 3pm. We were hiking the Kaaterskill Falls trailhead off Route 23A in Palenville, Catskills when we split up to take photos. She's wearing a bright yellow windbreaker, pink backpack, black leggings, and neon green shoelaces. She has a crescent-shaped birthmark behind her left ear. Last I saw her she headed toward the beech forest area near the falls, telling me she wanted a closer look at the water. I'm really worried and really hoping someone saw her.
