 When I first read the field notes of Annie Alexander and Louise Kellogg, I was fascinated by the descriptions they wrote about the places they went and the plants and animals they found there. By publishing my field notes on the Internet I hope to follow a little bit in their tradition.

Note on Smooth Brome One of the most common non-native species found at nearly every site was smooth brome (Bromopsis (Bromus) inermis). Smooth brome is not on the noxious weed list, yet it appears to be one of the largest threats to ecosystems, besides development, in Jefferson County, particularly in wetlands. Smooth brome is very difficult to treat without causing problems to the surrounding environment. Unfortunately, the spread of smooth brome is being encouraged by weed treatment activities especially in wetlands. Canada thistle is very common in wetlands, and is a B-List noxious weed. It is often treated with herbicides that impact dicots. Smooth brome is a monocot. A recent report by Rondeau (2011) found in a six year monitoring effort for Canada thistle (Cirsium arvense, also Breea arvensis) that although the treatments were successful in removing the Canada thistle it was replaced by smooth brome in wetlands where smooth brome was already in the area. In addition, they found the local native plants including woody species were being impacted as well over the six year study. Overall the result was a less desirable outcome than the situation being remedied from an ecological perspective. This is unfortunate because Canada thistle is a B-Listed plant; people are being required to treat it. If smooth brome is in the vicinity (which is often the case) a state listed noxious weed is being replaced by something that is even more difficult to control and arguably more damaging to the ecosystem. In the State of Colorado, smooth brome is available for use in seed mixes used by ranchers, homeowners and highway departments which is why it is not listed as an invasive species. This plant is considered to be an invasive species in at least ten other states (MN, OH, IN, IL, KY, TN, NB, WI, ND and MS), by Ivasives.org and The Nature Conservancy.

Dolmen de Matarrubilla

The Matarrubilla Dolmen was discovered in 1917, also as a result of some agricultural tasks. It is just one kilometer in a straight line from La Pastora,

As a funerary corridor and circular chamber structure with a total length of 32 meters, Matarrubilla approaches La Pastora in grandeur. It differs fundamentally because in the chamber is a great block of black marble, carved and with a recess of several centimeters on the upperpart, that probably fulfilled functions of table of offerings or altar. Undoubtedly it is a ritual element that already had great importance in the design and planning of the monument, since its placement, occupying much of the space of the chamber, must have occurred before the erection of the roof in a false dome.

The funeral deposit found in Matarrubilla was quite scarce. In the plundered chamber were scrambled and fragmented remains of pottery and some human bones. In the corridor, some materials were in situ, including stone tools, a large number of fragments of gold lamellae, some ivory objects (including an elephant tusk in the rough, unworked) and several thousands of necklace beads. Only one complete skeleton was found, halfway down the corridor and in a cramped position. The relatively low number of burials and grave goods and the presence of the altar or offering table that so clearly dominates the space available in the vaulted chamber of the monument suggests that, indeed, a monument such as Matarrubilla may have played the role of a temple or ceremonial enclosure besides (or perhaps more than) a sepulcher ( https://www.rutasconhistoria.es/loc/dolmen-de-matarrubilla ).
