Jon pursued BS degrees in math and science. His first job was as a high school math and science teacher and coach of golf, tennis and junior varsity football. He enlisted in the United States army where he served for two years as a combat engineer. He went on to earn a master’s degree in mining engineering and then devoted 30+ years to the commercial explosives industry. His roles included technical sales representative, plant manager, field trainer, safety and compliance manager, technical writer, editor and trainer. He was member of professional organizations Institute of Manufacturers of Explosives (IME) and International Society of Explosives Engineers (ISEE). After retiring from field work due to his visual impairment, Jon went on to become editor of the 18th edition of the ISEE handbook, authoring several chapters and managing 25 contributing authors over a five year period. This publication, widely recognized as an industry standard, is available in print and digital versions and is available in both English and Spanish.

Jon was very passionate about classical music, opera, southern gospel and sacred music. He and Linda attended countless concerts during their 25 year marriage. He was member of church choirs until his visual impairment prevented him from being able to see the sheet music or the conductor. He loved baseball memorabilia, the Atlanta Braves, cowboy westerns, television shows from the 1960s, Alfred Hitchcock mysteries and classic movies from the 1940s and 1950s. He loved to travel and collected maps, flags, stamps and coins from foreign countries. He was an avid reader who had collections of books including history, geography, biography and reference books.

The family would like to thank everyone for their love, prayers, visits, and phone calls. A heartfelt thanks to Hospice of Northeast Georgia Medical Center and Pruitt Home Health along with those caregivers and personal sitters who provided compassionate daily care.

He was a believer and a longtime member of Chestnut Mountain Presbyterian Church, 4675 Winder Highway, Flowery Branch, Georgia 30542. In lieu of flowers, the family requests that donations be made to the church general fund.

Jon had a keen sense of humor and brought a smile to friends and strangers alike. Jon always had a special place in his heart for the elderly and for people with disabilities. He was a kind and patient man who was generous with his time and his resources. He was a loving husband, father, grandfather and friend who touched the lives of many and will be greatly missed.

Russell F. Boren

In Memory of… Russell F. Boren – President ISEE 1992 - 1994

Russell F. Boren, Sr., 91, of Oneonta, AL., passed away on September 10, 2023. Russell loved Auburn, Blount County, all churches, and most of all – his family.

Russell was born and raised in Hayden, AL. He attended St. Bernard High School from where he graduated a semester early. He went straight into college attending St. Bernard Jr. College for three semesters. He went on to get a Civil Engineering degree from Auburn University in December of 1954.

Russell worked as an engineer in the late 50’s and early 60’s for Blount County. Russell worked for Debardeleben Coal Cooperation until he and his uncle formed Pawnee Construction Company. After five years, they left and started Dixie Drilling Cooperation in 1966, and in 1968 they also formed Apache Machine and Supply Company as well as Apache Construction. A little later in 1972, Russell also started Boren Explosives Company. In 1990, he formed a joint venture and worked with Dyno Nobel, until he sold them his part and Boren Explosives Company in 2018. After 50 plus years, Russell elected to liquidate both Dixie Drilling and Apache Construction in 2021. During this time, Russell was also in commercial real estate before he and his sons purchased Limestone Springs in 2020, after living there since 2008. Throughout his years, Russell also owned several coal mines, was involved in the trucking business, and owned Boren Trucking.

Russell served on the International Society of Explosives Engineers (ISEE) Board for many years and served as President from 1992-1994. His focus was on education. He was instrumental in the establishment of the SEE Education Foundation and served on the board of trustees of the foundation for many years. He was known to reach into his own pocket when the foundation did not have enough money to award every worthy scholarship applicant. Much of the work and development of ISEE’s Certificate Program - Level One took place during his presidency. This included maintaining relationships with and communicating with regulatory agencies to get the training approved. Rights to the Blasters’ Handbook was purchased from ETI, formerly Dupont, and ABA publishing was purchased which was the beginning of the Blasters’ Library.

He is preceded in death by wife Hazel Boren; son Fred Boren, Jr.; great grandson Connor Wilson. He is survived by son Patrick F. Boren; grandchildren Amanda Boren, Andrea Boren, Rachel Little (Kevin), Olivia Boren, Russell Boren III; great grandchild Ryder Little; brother Jerry Boren (Nelda); daughter-in-law Janie Boren; brother-in-law Charles Puckett.

The family would like to thank all the many employees throughout the years of all the Boren Companies.

Duane Straw

Duane Lewis Straw of Hill City, SD passed away on the morning of September 6th, 2023. Duane passed with his loving wife, Brenda Straw, by his side in their home. Duane and Brenda met in the summer of 1980 and Duane was immediately taken by Brenda. Duane fell in love with Brenda for her kind soul, witty personality, and beauty (inside and out). Brenda fell in love with Duane for his big heart, caring nature, and those beautiful blue eyes. Duane and Brenda would have been married for 42 years on October 24th.

Duane was born May 11 in Wallace, ID to the parents of Loite and Viola Straw. Duane grew up with his 11 other siblings in Hill City, SD. Annette and husband Duane, Hill City, SD. Floyd Straw and Mary of Fairburn, SD. Donna Coppess, Bellefourche, SD. Donald Straw, Rapid City, SD. Donavin Straw, Bridgewater, SD. Diane Vanderbeek and Gene, Provo, SD. Bonnie Goodroad, Nisland, SD. Dennis and Kiki Straw, Hill City, SD. Brothers deceased. Danny Straw, Hill City, SD. Ronnie Straw, Hill City, SD. Derwin Straw, Rapid City, SD.

Duane was a Driller and Blaster for many years. He worked Drilling and Blasting for Pacer Corporation, road construction, and spent the last 25 years of his career at Crazy Horse Memorial. He retired in 2016. Duane always spoke fondly about his time at Crazy Horse. He loved discussing the monument and you could tell how passionate he was about the work he did there. His wife Brenda put together a wall of pictures in his man cave, honoring Duane and all his years at Crazy Horse. She wanted him to know how proud she was of him. Duane was honored to know and work with the Ziolkowski family and his colleagues at Crazy Horse Memorial.

Duane was the proud father of two children Justin Straw and Amanda Jefferies. Amanda and her husband Ian live in Aurora, CO. Amanda, just like her father, always wanted to help people, and works for a national nonprofit organization that serves first-time low-income families. Justin and his husband Erick live in Box Elder and are the owners of Justin Straw Designs, which is one of the most reputable wedding companies in the Black Hills. One relative said that when Duane spoke of his kids you could always see in his eyes how proud of them he was. Duane was the loving grandfather of Elena, Dominick, Exavior, and Dayzee Long Wolf Straw. Duane loved his grandkids and was delighted to watch them succeed in all their endeavors.

Duane was loved by many and had several lifelong friends (you know who you are) who became family over the years. Duane loved swimming in Spring Creek, climbing Black Elk Peak & Mt. Baldy and enjoyed all the beauty of the Black Hills. But the thing Duane loved the most was throwing back a few beers with his family and friends and sharing a few laughs in his man cave. The family will celebrate Duane's life and his passing with a memorial late spring 2024, at his Man Cave and home. The family will provide more details as the time comes.

We love and miss you tremendously Duane.
