At the confluence of the Sonoran and Chihuahuan Deserts, where annual rainfall is less than 12”, there is an area teeming with life. Before Europeans arrived, the San Bernardino Valley was the site of the region’s most significant ciénega (desert wetland) unique to the southwestern US and northern Mexico.

When Europeans settled the area about 200 years ago the pressures of grazing, farming, mining, and beaver eradication began to deteriorate the land. When monsoon rains came, the water cut large gullies into stream and river banks, which drained the wetlands.

Learning from the past, CLO is repurposing erosion control technologies used by indigenous peoples in northern Mexico to restore these historic ciénegas. The two main methods include: trincheras (small rock dams) and gabions (wire cages filled with rocks) to restore riparian areas on a watershed scale.

I have the idea that the Tijuana River used to be a place like that. I used to go to this place in Tecate, Mexico, near Rancho Vacas Flacas, and there is no water, but it is all willows and must have once been a wetland marsh.

... and his posterity too? See  On Communication in Linear Time And Hypertext And The Gospel of Sophia . So it looks like El Cielo of the cistine [sic!😂] chapel is not the limit anymore.  I think I just met one of his descendents. A guy called Versailles Toledo who is from Chiapas. That might explain the murals I mention in my recent untitled post , just before the post mentioning this video. I also just took this photo of Rafael Gonzales, born here in Tecate, B.C., who told me about a spring near here called Agua Fría , half way from Tecate to Loma Tova , where, a few decades ago, people used to go to have barbecues and stuff, but now he thinks it may be private land. If someone reading this has a Facebook account, please write a link to this post onto his FB page. To see why I took the photo, look at his T-shirt and the horse-shoes and ponder this: Subscribe to BeatrizER and her video(s?) about mathematical logic, ...

This was in The Guardian: David Turner obituary , only eight days after I posted  David Turner Talking About Sixty Years of Functional Programming History : This talk was given in London in 2017: See  Turner, D. A. "Some History of Functional Programming Languages" also  John Hughes - Why Functional Programming Matters  and David MacQueen's talk at ICFP 2015 in  Numberphile - Sophie Maclean on the Catalan Numbers . At 10:30 This whole discussion abut combinator reduction is especially interesting. I didn't know Arthur Norman had tried building hardware for combinator machines. I'll look that up: maybe start here A.C. Norman  Faster combinator reduction using stock hardware  in LFP '88: Proceedings of the 1988 ACM conference on LISP and functional programming. At 26:25 on the ISWIM virtual machine implemented in the PAL compacting garbage collector?! This work Reynolds and others did was at MIT in Masecheusetts and Argonne National Laboratory ...
