Deer antlers growing incorrectly

Hi, we have many young bucks around here (near Conifer) that have their antler or the button growing oddly and out of place and wonder if you could tell us why? The button will appear off-center over the left eye usually, though some are growing out of the front of the forehead instead. Is this due to genetics, environmental toxins, injury, or something else?
Thank you so much, we are all curious!

What is this spider?

What is this small black spider? (photo attached) He does not seem to build a web but rather hunts for his food similar to a brown recluse. They frequent my garage at 9,500 ft of elevation in Taylor Park, CO. Thanks!

What are these?

Hello - I wonder if you can identify these "guests" and tell me what to do about them. We live in Colorado Springs, Colorado, and although I noticed one or two last week (when the outside temps go up and down, insects do show up indoors), they have been increasing for a few days. They seem to enjoy the kitchen sink best (I don't see any under the sink), but now they're beginning to explore the house. They look like pint-sized flies. They don't bite or make noise that I've observed. I've heard of drain flies, but I don't know anything about them. I would really like them to end their visit - they don't even have the excuse of being relatives! Thank you in advance for your help. Kind regards, (Mrs.) Mary Lichlyter

Prickly Pear Cactus Removal

I own 2.5 acres in Westminster, and the majority of the land is covered in Prickly Pear Cactus. What options are we allowed to do it in the least time consuming and least harmful way? We intend to turn portions of the land where there are cactus into an orchard, garden and grass so we are concerned with herbicide use especially with our dogs. We read about burning them, but I would assume that's not option in Colorado's dry climate? Any help is appreciated!

Soil amendment in the fall, or in the spring?

Hello,
I am a Master Gardener who moved from Salt Lake City to Montrose a couple of years ago. I've planted gardens here for two summers now, and have not had good outcomes. I'm going to put in a garden into the empty lot on our property; it will be about 25X35, full sun exposure, with plenty of irrigation water available. The lot has never been planted, plowed, or built upon. We're having a tractor come next week and plow it up for us to get all the large rocks out and to plow it 3 feet down. I'm fairly sure the soil will need to be amended so I want to bring in a couple loads of compost before planting next spring. When is the best time to amend soil here - in the fall before the cold weather hits and before the soil gets too wet, or in the spring when the soil may be muddy and hard to turn the compost in? thanks, I appreciate your help.
