Graduated: Piute High School 1956
Religious Activities: LDS Relief Society President
Civic Activities: Enjoyed community involvement, especially hospice help, with her Sorority sisters in Beta Sigma Phi
Hobbies and interests: As an avid reader, she particularly enjoyed historical fiction. She enjoyed travelling and shopping. Alcea went nowhere unless dressed to the nines, which included a never ending assortment of high heels that never left her feet. For a while, she sold Mary Kay cosmetics and jewelry.
Alcea loved spending time in Gilbert Arizona with her daughter Tara, where she basked in the heat that others tried to escape.
She loved to bake sugar cookies, and applesauce pie which would always be ready for anyone who happened to visit.
Nicknamed “Mrs. Clean”, she was constantly scurrying about the house tidying up, which meant don’t even place an unfinished drink down or it got magically whisked away.
If Alcea wasn’t in Richfield, she could be found at her beloved “Cougar Ranch”, the Anderson family property located 5 miles up the mountain from the city of Junction. She made sure all the cabins were spotless, and ready for the next guests with fresh linens and utensils. It was critical that all was ship-shape when it was time to make reunion memories and spend precious moments with family, friends and all who enjoyed the serenity of God’s country.
It’s probably a blessing that Alcea passed peacefully before witnessing the recent cottonwood wildfire that completely destroyed everything. The total devastation would have killed her from shock, sadness and grief.
Thankfully, we all have photographs and experiences to remember Alcea in her element.
