Archaeological Excavation – Site Visit Invitation

ERO would like to invite the local archaeological community and the ERO team to an on-going excavation that is taking place in Douglas County and near Reuter-Hess Reservoir. They would like to extend an invitation to the Denver CAS chapter and interested students.

Site 5DA3419 (sorry, no catchy name was ever given) is located along Oak Gulch, a small tributary of Cherry Creek and a short distance east of Newlin Gulch where significant sites were excavated prior to construction of Rueter-Hess Reservoir (RHR). The site has both Early Ceramic and Middle Archaic components – very similar to the components recovered from the RHR sites. Currently, the excavation has exposed primarily the Early Ceramic component, with an abundance of cord-marked ceramics and corner-notched projectile points typical of the period. Numerous thermal features have been exposed and recovered. Unfortunately, we have yet to uncover pit structures similar to those excavated at RHR. Hopefully they will have some interesting features still exposed by the end of next week (they will leave some features in place, as well).

The site visit is scheduled for Friday, April 21st. We will be meeting at 10 am at the entrance gate to Reuter-Hess Reservoir. A KMZ file is available with this location from Sean Larmore. We will then consolidate into vehicles and caravan to the site. Some cross-country travel with high clearance vehicles is necessary. Because the site is not readily accessible to the general public, the meeting time is firm for all participants. In the event of rain we will not be visiting the site but will have to reschedule.

ERO understands the relatively short notice and that some interested folks may not be able to attend on this date. Depending on results, they may schedule a second site visit at the end of April or early May.

Please RSVP back to Sean Larmore by Wednesday so he has an idea of how many people will be attending.

PAAC CLASSES – Denver Chapter, 2017

The winter PAAC Lab certification classes will be held at the El Pueblo Museum in Pueblo. The lab will occur on Wednesdays, from 10 AM to 4:30 PM, beginning in late February or early March. Volunteers will be working with two students from CSU-Pueblo who are completing and internship related to their studies in anthropology. Volunteers will be working on cataloging, analyzing, and curating an extensive historical artifact collection from excavations at the site by the late Dr. William Buckles. If you have and interest in this class please contact Chris Johnston, Assistant State Archaeologist, (

The PAAC summer training survey is slated for July 2017. This summer we are partnering with Paleocultural Research Group (PCRG) to do an intensive survey, testing and rock art recording project in the San Luis Valley. Participants will have the opportunity to get experience conducting survey and testing, recording and documenting sites, and working with volunteers and professionals from across the state. The Valley has a rich archaeological past, spanning from Clovis to Hispanic settlement and farming and ranching; we are very excited about this partnership and look forward to you joining us. A field camp location is being explored in or near Antonito and details will become available soon. Participants will be provided tent camping accommodations during each project session and all meals will be provided. There will be two sessions: one from July 8-15 (arrive the afternoon of the 7th), and one from July 20-27 (arrive afternoon of the 19th). More details will be announced soon but if you know you are already interested please contact Chris Johnston, Assistant State Archaeologist, (

FIELD TRIPS – Denver Chapter, 2017

Tuesday, April 25:  Work day at Casa Colorado, Casa Blanca, and Inaccessible House Trail Work

Wednesday, April 26:  Work day at Porcupine House (work on cleaning out and repairing concrete diversion dam above ruins); and, if time, remove fallen trip across trail in North Lion Canyon between Tree House and Lion House

Thursday, April 27:  Exploring rock art sites in the Park including Atl-atl Point, Kiva Point, Chief Jack House Hogan site, the Train Site (if Mancos River isn’t too high to cross), and others.

NOTE that there are TWO work days.  The Tribal Park is offering a tour to Casa Colorado, etc. on their Open House day May 27.  There is NO trail there and lots of scrub oak!  We are to make it somewhat easier, if possible, to access those sites.

If you want to know more about the Tribal Park, here’s their website:  For their info on the Open House, go to the Printable Flyers link on the left.

I am rating this trip as moderately strenuous due to amount of walking carrying tools (Casa Colorado), elevation (~8,000), and terrain (rocky, scrub oaky).

New unique PPC/CAS Field Trip Announcement – Open to Pueblo and Denver CAS members, family and friends – Saturday May 13th – The National Museum of WWII Aviation in Colorado Springs

PPC/CAS invites your members with their family/friends to join us for a field trip and lunch (pay your own way) on Saturday May 13th.

Are you interested in World War II history and airplanes? We have a field trip for you! PPC/CAS member Rick Schlegel has made arrangements for our chapters to have a guided tour of the National Museum of WWII Aviation. Some of the restored aircraft were dug up in New Guinea where they had been buried by the US after the war, or where they crashed, so they are really are archaeological artifacts in the true sense.

The National Museum of World War II Aviation is home base for more than 30 aircraft, most of them fully restored to flying condition. The Museum’s aircraft are displayed along with a selection of aircraft on loan from private collections around the country to tell the full story behind American advancements in aviation technology during the war.

We will be heading to the museum at 755 Aviation Way, Colorado Springs, CO 80916 (Google Maps link on Saturday May 13. We are meeting in the parking lot of the National Museum of WWII Aviation by 9:30 am, tour begins at 10:00 am for 2 hours. We will see the museum and West Pac Restorations. The cost is $8 per person if we have at least 10 people or over 65 or military; otherwise the fee is $10.  After the tour at the aviation museum, we will continue to learn more about planes when we proceed to the Airplane Restaurant for lunch (you pay your own way). We have a reservation for 12:45. The Airplane Restaurant centerpiece is a fully intact Boeing KC-97 tanker. Built in 1953, this magnificent airplane refueled aircraft throughout the world such as the B-36, B-47 and B-52.

If you will be attending this fun tour of aviation archaeology, sign-up at the PPC/CAS General Meeting next week on April 18th OR by sending email to Rick Schlegel or Judy Kilgore with the number in your party and if you will be joining us for lunch after the tour. Remember, if we get at least 10 people, the cost for the tour will be $8 per person. We are looking forward to the fun tour of an important part of our history!

NOTE! There is no limit as to the size of the tour group. This field trip is OPEN to family and friends plus the Denver and Pueblo CAS Chapters!
