Cherry Creek High School student wins national Trig-Star competition!
Posted July 16, 2014

State competition winners from 37 states participated in the recent national 2014 Richard E. Lomax Trig-Star finals, sponsored by NSPS. Lomax, the 1992 NSPS President from Michigan, was a driving force in making Trig-Star a national program. Trig-Star begins each year when local surveyors work with teachers (typically math teachers) in one or more high schools in their respective communities throughout the U.S. The surveyor gives a presentation to the students about surveying and its importance in the world. The students then solve a predetermined math problem. All local winning entries are compared, and the student with the highest score achieved in the shortest amount of time is deemed to be the state winner. State winners then participate in a second (national) competition. The 2014 national winner solved the test question correctly in 18 minutes, 30 seconds. Several competitors solved the question correctly, therefore the time element became the deciding factor.The 2014 national award winners are: 1st Place - Lubin Deng, Cherry Creek High School, Greenwood Village, CO (teacher, Dorothy Dady); 2nd Place - Benjamin Fawcett, New Hanover High School, Wilmington, NC (teacher, Nicholas Corak); 3rd Place - Natalie Sanchez, Rochester High School, Rochester, WA (teacher, Carolyn Johnson). The winning students, and their teachers, receive a monetary award and a plaque recognizing their accomplishment. NSPS expresses its sincere appreciation to the surveyors who worked so diligently as local sponsors, and/or as state coordinators. Without their efforts this important program could not continue to prosper. Thanks also to the NSPS Trig-Star committee for its dedication to the program.

Member Spotlight

PLSC would like to introduce you to our members. If you would like to submit your photo and information for a future Spotlight, email the information to

Laine Landau, PLS - Laine’s interest in land surveying started in her Ohio 3rd grade classroom where she learned about metes and bounds descriptions, 3, 4, and 6-mile townships, and the development of the modern PLSS.  When Laine started at Flatirons in 1986 there wasn’t any drafting software for surveying so it was mostly done by hand. Fortunately AutoCAD and the related software soon evolved.
Laine credits the PLSC refresher course as the official start of her transition from draftsperson to professional land surveyor. She passed the LSIT exam in 1993 and the LS exam in 1996.
Laine was primarily involved in boundary and title analysis, drafting, and managing development projects in Boulder for Flatirons Surveying and Flagstaff Surveying, and Nolte Associates and TST in Fort Collins. She is presently with William H. Smith & Associates in Fort Collins working in the oil & gas industry which has taken her work into remote areas where section breakdowns involve township retracements, fractional sections, original monuments, and some unique pincushions (Indian allotment monuments, USGLO monuments, and marked stones touching).
Laine has been an active member of PLSC since 2000 and is currently the President-Elect of the Northern Chapter.
