Painting the 'A' Sept. 10

September 9, 2009

Painting an 'A' that is 450 feet high and 210 feet wide is no small chore, but Colorado State University students have always been up to the task. On Thursday, Sept. 10, students will leave from Moby Arena (transportation is provided) to 'A' Mountain for the annual painting of the 'A.'

Thursday, Sept. 10
8:15 a.m., 10:15 a.m, and 12:15 p.m.

Students paint the 'A' in September of 1927.

Painting the 'A' is one of CSU's oldest traditions. Live the tradition by painting the 'A' this week! Register today and do your part in preserving the tradition. Space is limited, so make your plans now!

A long-standing tradition

Painting the 'A' white began as a tradition in 1924 - after the emblem had been enlarged. It continues as a tradition today, thanks to the Student Alumni Connection, the College of Agricultural Sciences, and members of the freshman football team and Sigma Alpha Epsilon Fraternity

  • The 'A' serves as an aerial landmark
  • Pilots can see the 'A' from as far as 60 miles out
  • Each summer, as a part of Ram Welcome, freshman hike to the 'A' and leave a small white pebble as a symbol of the impact she/he will have on the University
  • The 'A' is painted with non-toxic white paint that is checked and deemed environmentally sound by CSU's Environmental Health Services.

Fun facts about the 'A' 

  • The 'A' stands for Aggie, one of the former mascots for the University
  • Construction of the 'A' began on Dec. 12, 1923
  • It took six hours to complete
  • The land used to construct the 'A' was leased to the University on a long-term lease for $1
  • On Sept. 20, 1924, the dimensions of the 'A' were expanded to its current size of 450 feet high by 210 feet wide
